Problems with a Page

Hello Squid users! :)

I'm new using squid and currently doing some test...

I have squid 2.1.PATCH2 running on a Ultra1 with Solaris 2.6

My problem is that I need to access an specific URL
http://www.banxico.org.mx/public_html/inveco/infecon/smonyfin.html#Total
This page contains a set of checkboxes that are used to obtain
specific information via a CGI program.

When I try to get it with a Direct Internet Connection (without proxy)
all results Ok, but when I try to get it using squid, the connection
simply times out. :(

If use a Netscape Proxy the page works, so it seems to be a Proxy's
problem. But I want to do the job (obviously) with Squid...

Any pointers to test or configure to solve this?

Thank you in advance for your help.

Regards.
