Re: newbie question about large post requests

Thanks Amo for your fast reply,

I meant it ignores the POST requests, I can access the requested page
normally but with no post parameters. So, If I want to navigate
through the website using POST, I can't and I get only the first page.

Actually I didn't change any configuration !!

Squid Version and Configuration options:
Squid Cache: Version 3.0.STABLE16
configure options:  '--build=i386-redhat-linux-gnu'
'--host=i386-redhat-linux-gnu' '--target=i386-redhat-linux-gnu'

But I don't know how to get the HTTP headers of the traffic between
squid and the spider. Can squid log such details ?

Finally, the spider is trying to access this website, navigate on it
using post requests and parse the data. When I use the spider without
squid, it works like a charm, once I use squid, the post problem
occurs.


Thanks again
