Let your ASP ASP running on Apache
ASP running on your non-Windows platforms since the launch of Micorsoft ASP technology, the ASP to create dynamic interactive site in the power and simplicity of coding, so that more and more ASP Internet / Intranet / Extranet site get a very wide range of applications, particularly in relation to the operation of the website database applications using ASP technology is preferred. However, due to reasons known to all, ASP only work on Microsoft's Windows NT platform + IIS Web Server server software, Windows9X + PWS can use, but can only be used for debugging or learning, which will determine the limitations of ASP applications. According to the data using the Windows operating system platforms and server software Web site at about 15%, that is, Nearly 85% said the site will not be using ASP technology. most of the commercial Web site uses a Unix, Linux, Soris and Netware operating systems and the corresponding server, indicating that the application of ASP technology is very limited indeed. Do not be applied to non-ASP for Windows platform? Of course not. So far we have at least two options, Chilisoft4 the company's chili ASP and Halcycon company iASP (Instant ASP). Halcyonsoft companies to developed iASP, so that ASP can not only use Windows operating system platforms and server software used on the website, you can also use other operating systems such as Unix, Linux, Soris, Netware server operating system and the corresponding use of the website. iASP comprehensive inherits the advantages of ASP and is fully compatible with ASP, ASP applications which can be directly ported to almost non-Windows operating system platform running under the iASP environment, making the ASP application to become a truly cross-platform Internet, Intranet or Extranet applications. iASP compared with the ASP, not only in support of the operating system platform has an advantage in the use of third-party components to build ASP applications on the system also has obvious advantages. iASP not only support the popular ActiveX components, support for the popular Enterprise JavaBeans components, and CORBA-compliant components in order to use ASP applications more powerful, more broad. In addition to MS Visual series of development tools and Borland family of development tools, you can also use the Java family of development tools so that component developers more options which can be more handy to the development of related components. iASP There are two versions, one for Windows operating system platforms and server software, another for Unix, Linux, Soris, Netware operating system and the corresponding server software. The latest version is 1.0.9, has just launched a Linux version of the FREE, you can free download on the site, its function is basically the same compared with the official version, in particular in the network to Unix, Linux to use local area network ASP Web developers may wish to download a trial about the file size more than 9M. A, iASP iASP software requirements software environment is entirely compiled from the Java programming language, you need the support of JDK1.1.X or above, and thus JDK1.1.X need to pre-installed on the system or later. Linux platform under the JDK11.X can download the platform-based Windows9X/NT download address ftp://202.103.111.173/Download/ JDK1.1.X DEVELOP/JAVA/jdk1_1_1-win32-x86.exe. also need the appropriate Web Server software, such as IIS, Apache, Netscape, Xitami, Sambar and so on. Second, iASP installation support system software platform and server software is to use JAVA programs iASP compiled language, in principle, can be run on all JAVA platforms. iASP can automatically configure the server software so that it can use ASP pages iASP interpretation and conversion; iASP can use Halcycon iASP Servlet developed software interfaces with the server connection and communication, you can also use other Servlet interface to connect and communicate with the server. iASP supports the following platforms and Web Server: (a) Sun Solaris Sparc platform 1, Apache server software, Apache server software can iASP the 1.3.0,1.3.9 , 1.3.11,1.3.12 in nine commonly used version of the automatic configuration to make use of ASP pages to explain iASP; iASP the Servlet through the interface connected to it and communications. 2, Netscape Fast Track (FT) and Enterprise Server (EP ) server software iASP can FT3.0.X, EP3.5.X, EP3.6.X automatically configure to explain the use of ASP pages iASP; iASP the Servlet through the interface connected to it and communications. 3, Sun Web Server2.1 server software on the Sun Web Server2.1 iASP can automatically configure the server software so that the use ASP pages to explain iASP; and through the Servlet server software and communications interfaces connected to it. 4, Zeus Zeus server software server can iASP software for automatic configuration engine to explain the use of ASP pages to explain iASP; and through Zeus and Apache JServ Servlet interface, connectivity and communication with them. (b) Sun Solaris Intel platform 1, Apache server software, Apache server software can iASP 1.3. 0,1.3.9,1.3.11,1.3.12 automatically configured in nine versions of the ASP page to explain the use of iASP; iASP the Servlet through the interface connected to it and communications. 2, Sun Web Server2.1 server software Sun Web Server2.1 iASP can automatically configure the server software so that the use ASP pages to explain iASP; and through the Servlet server software and communications interfaces connected to it. 3, Zeus Zeus server software server software iASP can be automatically configured so that ASP pages use iASP interpretation; and through Zeus and Apache JServ Servlet interfaces that connect and communicate. (c) Novell Netware platform Netscape Fast Track (FT) and Enterprise Server (EP) server software iASP can FT3.0.X, EP3.5.X automatically configure to explain the engine to explain the use of ASP pages iASP; and through the Novell Servlet Gateway interface to connect and communicate with them.

(viii) SGI server software platform iASP Zeus Zeus server software can be automatically configured to make use of ASP pages to explain iASP; by Zeus and ApacheJServ Servlet interface to connect and communicate with them. Third, ASP applications built with the environment iASP assumption that the system has been properly installed and configured TCP / IP and other network protocols. below to RedHat Linux 6.0 and Apache 1.3.9 server software an example to discuss how to install and configure iASP, to establish a development and application of ASP environment. (a), Apache 1.3.3 server software 1 installation, the installation server software Apache 1.3.3 Apache 1.3.X if the server software is not at hand, you can to download a. 2, start the Apache 1.3.9 server software with the command to start Apache 1.3.9 httpd server software. start Apache 1.3.9 server software can be used after the Netscape Communicator browser, or a way to access the Apache 1.3.9 services provided by the WWW server software. The default page is index.html, usually located in , page theme must install the JDK. 1, to determine the type of C runtime Liunx / Unix version of the JDK are generally two versions of libc5 and glibc to adapt to different Liunx / Unix systems in the C runtime library version. with the command lib / libc.so .* type of glibc. I used RedHat Linux 5.1 the C runtime type of glibc. 2, download the installation JDK1.1.12 JDK1.1.12 in the glibc version, and renamed jdk112.gz. will jdk117.gz copied to / usr / local directory, enter / usr / local directory, use the iASP to download the Linux version in the iASP, and copy it to / usr / local. with the command / local directory, run. / install.sh, follow the installation program prompts to complete the installation iASP. during the installation process, the need to specify the JDK's BIN directory (/ usr/local/jdk117_v1a/bin) and iASP installation directory (/ usr / local .) installation process is complete, will choose whether to proceed on the Web server configuration, the configuration process is discussed below, choose The role of the file note. connector.sh: iASP automatically start the configuration wizard start-server.sh: Start iASP proxy server stop-server.sh: Close iASP proxy server start-admin.sh: Start iASP remote management server stop-admin. sh: Close iASP remote management server (d), the configuration iASP 1, close the Web server configuration during the iASP, should first turn off the Web server software. 2, configuration iASP iASP configuration wizard for the Apache server software, Netscape Enterprise Server software, Internet Information Service server software for automatic configuration, and Zeus, Sun Web Server server software is not required. in / usr / local / iasp, run. / connector.sh iASP configuration wizard starts. Select ; select the server software and version (Apache 1.3.9), Apache httpd.conf configuration file directory (/ etc / httpd / conf), the other may remain unchanged (press enter the default setting). whether the prompt Another server's configuration, select nxterm window in the directory / usr / local / iasp run. / start-server.sh, start iASP Connector Proxy proxy server program. 2, test iASP start Apache 1.3.9 server software. in the browser column enter: or http : / / 127.0.0.1/iasp that you can see examples and iAS iASP with some documents, it is quite detailed. example of a more comprehensive, with General, Form, File, Server, ADO, Email, etc., you can click to look actual results. for the outside world and you feel it is what the difference between IIS. At this point under the Linux platform and application development environments iASP set up, you can enjoy your intelligence to go play.

Deficit out of the way unemployment and high interest rates during the low probability of the United States
Since November 3, 2010 a new round of the Fed since the introduction of quantitative easing, the Federal Reserve released a large-scale mobility of full 3 months. In the global commodity and raw material prices in the context of emerging economies have entered the interest rate cycle has been on the market investors bet the Federal Reserve to raise interest rates are increasing.
interviewed analysts pointed out that the U.S. interest rate increase in the first half of 2011, conditions are not yet mature, because the lag of economic indicators, the Federal Reserve to raise interest rates as early as December 2011, but full-year 2011 the possibility of interest rates are very small.
quantitative easing inflationary worries
2010 11 3, the Fed issued QE2, the move did receive the results. The latest statistics show that U.S. manufacturing PMI in January to February manufactures 60.8,12-than-expected industrial orders in Central which was an increase of 0.1%, far better than expected 0.5% decline.
However, the U.S. economy is still facing many challenges. In addition to the release in order to save huge amounts of liquidity crisis, the public data also show that as the main way of financing the U.S. government, the U.S. national debt, 13 trillion-dollar, guaranteed by the U.S. government has 11 trillion real estate bonds.
the U.S. government's budget deficit has been high in recent three fiscal years were as high as 1.6 trillion, 1.56 trillion and 1.42 trillion.
SW Futures (Hong Kong) executive director, said Zhang Minjie, QE2 implementation means that as of June this year, the Fed delivered monthly to the real economy of up to 110 billion U.S. dollars of liquidity, the U.S. short-and medium-term inflation highlights the pressure, the dollar has become a major long-term depreciation of the probability event.
concerned about unemployment and CPI
It is reported that high unemployment and debt have become troubled by two major problems the U.S. economy, which restricts the Fed and monetary policy stimulus quit turning point in time choice.
conditions on U.S. interest rates, macroeconomic analyst at Western Securities that the Yan-Zhao, CPI reflects the terminal needs as the most important indicator of future U.S. monetary policy will become an important turning point for observing.
drive revenue increased as a precondition.
U.S. Labor Department released the latest data showed the U.S. unemployment rate fell to 9% in January, better than expected 9.5% over the same period last year, the U.S. unemployment rate has hovered around 10%; the same time, in January of non- Agricultural employment increased 3.6 million, far below market expectations of 13.6 million people.
von GF bright futures gold analyst said the U.S. job market is still improving, but not less than 8% unemployment rate will also maintain a minimum 2 years of historical data shows that the Fed has never been unemployment rate of over 9% interest rate.
Win Lose kinds of things.
unlikely to raise interest rates this year
food and commodity prices continued to rise, investors expected interest rate increase in advance.
interviewed analysts pointed out that the U.S. interest rate increase in the first half of 2011, conditions are not yet mature, because the lag of economic indicators, the Federal Reserve to raise interest rates as early as December 2011, but full-year 2011 the possibility of interest rates are very small.
Feng Liang pointed out that although the Fed did not loose the second time and the scale of quantitative ceiling, but the market is expected under the most optimistic scenario, the second quantitative easing will end in June 2011.
Feng Liang said, the effect of the implementation, so interest rates at the earliest to December 2011, so the possibility of raising interest rates throughout the year are very small.
