Re: windows 2K + IIS 5.0 + cgi program + HTTP connection Keep Alive doesn't work
Hi, Scott Sorry to bother you again. I've runned more tests, and found that for *.html files connection is kept alive, while for cgi program, it always close connection. Even when I just change my cgi program name with .html extension, connection becomes alive though the displayed content is in a mess. I've tried a simple html file and a cgi program which just produce the same html file. The *.html file works fine(I mean connection keeps alive) while not the cgi program. Also I found that in the HTTP GET header by Inetnet Explorer there is one: If-None-Match: some random value here, and in the reply by IIS there is a ETag: same value as in If-None-Match. Are such headers defined in HTTP 1.0 or 1.1? Related to connection problem? Thanks in advance! Xuemei

Sorry to bother you, but I really need some help soon. I just begin to use windows 2k Server and IIS 5.0 for my cgi program. The problem is that the HTTP connection Keep Alive is ON(by default), and the POST request to my cgi program also ask for Connection: Keep-Alive, but IIS always close the connection after sending reply to each request. There's no error at all, and even data is sent back though it's expired to Sender. How can I make HTTP 1.1 persistent connection work with IIS 5.0 on Windows 2000 Server? In fact, I have same problem with IIS 4.0 on NT 4.0 Server. Thank you very very much for your kind help! Xuemei
Re: windows 2K + IIS 5.0 + cgi program + HTTP connection Keep Alive doesn't work
Scott, Thank you very much for your help! I've posted my question to both tomcat-user and tomcat-dev newsgroup before I sent to you. Here I'll tell more about my program: System: Client Firewall --- [ Web Server - cgi program - mux server ] --- Another Server the data flow for each HTTP POST request as follows (obtained from LanWatch32): The firewall(Raptor) HTTP proxy tends to send one POST request in two parts: HTTP header + HTTP content client(firewall) Web Server cgi program + mux server POST path to cgi program HTTP 1.1 other headers Connection: Keep-Alive --- HTTP 1.1 100 continue .. HTTP content it may take cgi program 1ms --- 100ms to process and send back HTTP reply HTTP 1.1 200 OK .. other headers Connection: close HTTP content It happens both on Windows NT + IIS 4.0 and on Windows 2000 Server + IIS 5.0. My program works with Apache + Linux, the connection is never closed if set accordingly. My questions are: What's the parameters related to HTTP 1.1 connection? How to change them? Appreciate very much your kind help!
