The WebSpeed Messenger resides on the Web server machine. It is a process that handles the transfer of data between the Web server and the WebSpeed agent during a single Web transaction. The Messenger is either a CGI program, or an ISAPI or NSAPI process.
There are four different WebSpeed Messengers:
CGIIP Messenger — Runs on almost all Web servers, but tends to have the slowest response times.
WSASP Messenger — Calls WebSpeed applications from a Microsoft Active Server Page. It cannot coexist with any other Messenger on your Web server.
WSISA Messenger — Runs on Microsoft IIS Web servers.
WSNSA Messenger — Runs on Netscape Web servers.
You can use OpenEdge Management to edit the Messenger's properties.You cannot, however, create or delete WebSpeed Messengers from OpenEdge Management.
