why HTTP profile reset my web downloading

we got a very very painful issue, here is the story:

 

we have one F5 LTM 6800 device hosting our website. there is an iRule for this VS, related to http redirection based on URI. So this iRule requires http or fasthttp profile. however fasthttp will do source client IP translation, so we have to choose http profile.

 

here comes the problem, once we set http profile for this VS, the downloading from this website always fails. the client connection got reset at the very ending of download. we've tried to tune all kinds of setting in http profile, but that doesn't help.

 

anybody has similiar experience? any advice will be highly appreciated.

    I don't think the FastHTTP profile was designed for production use--I heard it was designed for performance testing.

     

     

    I'd suggest opening a case with F5 Support on this. Here are some of the questions it would help for you to answer:

     

     

    Can you capture a binary formatted tcpdump of the failure? When you're using the HTTP profile and getting resets, who sends the reset? Is it LTM sending RSTs to both the client and server? Or the server first? Are the RSTs sent after a timeout period? Does the failure occur on every HTTP request? Or all POST requests, or some POST requests which generate a large response? Is the client a standard browser? What type of server is it?

    thanks for hoolio's reply, you're right, we've opened a case with F5 40 days ago, but they haven't solved it yet..

     

    it's F5 sending the RST, and the failure only happened to http stream downloading. all clients are using MS IE and server is Win2k3.
