ASA blocking long URL access

[paulnigel]

Hi Forum,

I can't seem to find an answer for my ASA blocking long URL access. below is the only http filtering configurations i can find on my firewall. could it be the default settings? How do I turn it off, Is there a better way?

I am using ASA5500.

Thanks much,

paul

Do you have any filter http commands and url-server commands configured? If so, there is an option to truncate long URLs.

Also, bugs appear to exist in the http inspection engine in releases after 7.1(2). Try disabling the http inspection and see if the problem disappears.

Hi Andrew,

Thanks much for your help. when I turned off the http inspection, the error is gone. I do not have any filter http commands and url-server commands configured.

however, my firewall version is 7.0(4), is there a bug for this version?

thanks much for your help,

paul
