[squid-users] Problem when Submiting Information

Good Morning again, my squid proxy server is acting strange:

When i go to a page it works with no problem, but when i access example
yahoo, and do a search it doesnt do anything its giving me:
Error
FW-1 at ob1: Access denied.

This error is when you dont authenticate on the last firewall before to
go outside. But any other page it works, only when you SUBMIT
information, like Yahoo, hotmail, Google, etc.. Anyone experience any
issues?

thanks for your help
