Release 10.1A: OpenEdge Application Server:
Administration

Installing the Messenger executable

The WebSpeed Messenger must reside on the same machine as your Web server. The Messenger executables are tailored to run with a specific type of Web server. WebSpeed provides a Messenger executable that supports the Web server types described in Table 9–1.

Table 9–1: Windows NT WebSpeed Messengers 

Web server Type	Messenger	Messenger executable
Microsoft IIS	ISAPI	wsisa.dll
Microsoft IIS	WSASP1	wsasp.dll
Netscape	NSAPI	wsnsa.dll
CGI-compatible	CGI	cgiip.exe

1The WSASP Messenger calls WebSpeed applications from an Active Server Page. It cannot coexist with the ISAPI Messenger.

The NSAPI executables reside and run from the install-path\bin directory. The CGI Messenger and ISAPI executables reside and run from the \scripts directory on the Web server.

You can use the sample file cgiip.wsc to set up a file association for running the CGIIP Messenger under Microsoft’s IIS Server. For details, see the cgiip.wsc file, which is located in the install-path\bin directory.

Note: You must restart an ISAPI or Netscape NSAPI Web server after installing and configuring the Messenger.

Compatibility with the Web server type and operating system

The Messenger executable comes with the WebSpeed Transaction Server. The Messenger is installed in the scripts directory of the Web server, which you specify during an OpenEdge installation.

If you install the WebSpeed Transaction Server on an operating system that is different from the operating system that runs your Web server, go to the Download area on the PSDN Web site at http://psdn.progress.com/downloads/ and download a compatible Messenger. This is necessary because you must install a Messenger that is compatible with the Web server’s operating system. For example, if you are distributing WebSpeed components across networked machines and your Web server is running on UNIX, be sure to install a WebSpeed Messenger executable that is suitable for running on UNIX. Make sure that you download a Messenger for the appropriate UNIX platform and for the appropriate Web server type.
