CSS11503 discarding packets

Hi i have a service for port 8002 defined on my css and i'm seeing some soap posts being discarded by the CSS even though they work when they go directly to the back end ip addresses I port spanned the uplink and i can see the packets coming in but nothing getts sent to the backend? what is the css doing is it checking the HTTP header format?

if i encode the posts using a diffrent script they work.

Re: CSS11503 discarding packets

If this is a L3 or L4 rule the CSS doesn't care about the format.

However, if you ask the CSS to match a url, or find a cookie, making the rule L7, then yes the format needs to be correct or the packet is silently dropped.
