Hi, There was a similar bug that had been fixed in 2.2.4+ : https://issues.apache.org/bugzilla/show_bug.cgi?id=37770 Maybe you should consider to upgrade ?

The only problem that still persists is related to a specific intranet service that is hosted in IIS. For the first time, it works fine. But after a few minutes, the user gets the following error in the browser: ______________________________________________________________________ Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /wtouch/wtouch.exe/index. Reason: Error reading from remote server ______________________________________________________________________ Hitting the refresh button a few times successfully loads the page but, after a while, the problem happens again. I've searched for possible solutions, without luck; there are some people reporting the same problem (for example http://www.usenet-forums.com/apache-web-server/42208-proxy-error-apache-2-0-50-reverse-proxy-iis.html) but with no answers. The version of httpd is 2.2.3, the one that comes with CentOS 5.2. Thank you very much for your attention, cheers, AP --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
