Hello all,
We have two web servers that are being load balanced with this configuration on two CSS11503 with IOS version 7.20 Build 206;
content Web
add service web1
add service web2
vip address 10.1.4.4
protocol tcp
port 80
url "/*"
advanced-balance sticky-srcip-dstport
active
When we try and access the web servers from client workstation using the URL on Internet explorer 6.0 and get authenticated through the login window; we get error 12031. Error 12031 means " ERROR_INTERNET_CONNECTION_RESET The connection with the server has been reset. "
On refresh the error goes away.
If we bypass the content switches by accessing any of the servers using server name; the error does not appear. The problem seems to be related to the load balancing.
Any suggestions?

Did you take a trace to see what is occuring. Does the server send a RST or redirect back to the client to initiate a new TCP connection ?
The CSS is simply forwarding back the response from the server..

We use a tiny application called 'httpwatch' on the cleint PC. Its a pluggin gets added to the IE and can show the dns resolutions, http request/response codes,cookies information received, etc...
NB: I am not affliated to whvever making the product but I am just an end user.

the problem is probably due to CSS sending an HTTP redirect with the RESET flag when you send multiple request inside the same connection.
To avoid the proble, do a 'no url' under your content rule.
There is absolutely no need to specify the url since you do stickyness based on source ip address.
