NimbostratusI am having a problem with a URL being blocked by my F5's because the URL is too long.
What is really happening is the URL is short but then there is an advertising tracking code appended to it ( ?CMPID= ) and that is a really long tracking code.
is there a way to ignore everything to the right of "?CMPID=" ?
that way the URL would actually be seen as the correct length?
CirrostratusHow is this error reported to you please?
Are we talking LTM or ASM too?
NimbostratusASM
actually, the error is "Illegal parameter value length" and the parameter is CMPID
CirrostratusOK, so it's the query length (everything after the ?) (rather than the URL length) that is causing this violation. You need to edit your policy, go to Configuration > Advanced and find and modify the setting for 'Illegal query string length'. You can turn this off I guess or just enter a value that will stop causing you issues.
You could also use an iRule to get rid of the query entirely but I'd say thats not ideal and makes things more complex.
NimbostratusI went to Security/Application/Security/Policy Properties Tab and the to Configuration/Advanced screen but there is no setting for 'Illegal query string length'
I am in ver 11.3 hf8
