NimbostratusPerformance problem on Proxies LTM Balance
Dear All,
I need support for a problem we have with 2 Virtual servers.
We balanced a couple of Proxy with LTM.
We created 2 specific Virtual Server, one for the proxy.pac and another for the proxy itself
Both are configured with basic configuration in this way
Protocol --> TCP
Protocol Profile (client/server) --> tcp
HTTP Profile --> http
HTTP Proxy Connect Profile -->None
Source Address Translation -> SNAT
Access Policy --> NONE
Acceleration --> NONE
At the beginning with only 300 clients, all worked fine, but when we added more clients, a problem often started
The client tries to open a new web page (not cached locally) and the Chrome browser shows for some instant the error "404 Page not found" and after that, the page is loaded correctly.
If the clients use the proxy directly and not via LTM the problem doesn't happen.
We think LTM is caching something wrong, but we are not sure about that.
Does someone have a suggestion how to right configure this Proxy Balance?
Thank you

MManolliAfter some tests, the problem seems a timeout Server side.
We think , the client report a 404 error because the proxy take many time to reply to the F5 LTM request.
I'm trying to understand how to change the Request timeout in server side in order to workaround this problem.

A 404 Server Not found message is a direct response from the server and not the F5.

2019F5....... you are correct.
The message error i reported was wrong
The right message is "ERR_CONNECTION_RESET"
I created a specific TCP Profile in order to have a different Timeout value, but this don't solve completely the problem.
IT seems the proxy use a lot of time to analyze the java script in the remote site and this delay the reply to the F5 (LTM) causing the client side session reset
