I am using squid3 as our proxy server.

Now we (all PC in the network) has issue to access VirginAustralia.com.au. I can open main page, but when I click "Find Flights", It is shown the following:

============================================
"The following error was encountered while trying to retrieve the URL: http://book.virginaustralia.com/Search.aspx


Read Error

The system returned: (104) Connection reset by peer

An error condition occurred while reading data from the network. Please retry your request.

Your cache administrator is webmaster.
"===========================================

In our squid configuration, we don't have block list for any website or IP.

Besides of cleaning the squid cache, anything else I can do? like add the URL to bypass the squid?


Here is squid3 access log:

Can you open the .com URL referenced in the error directly?
Www.virginaustralia.com?

no issue to access www.virginaustralia.com. as you can see the log..

http://www.virginaustralia.com/json/submission/findFlight.json - DIRECT/123.200.150.148 application/json

This is fine. but not the following:

1334531062.990  18020 192.168.8.3 TCP_MISS/000 0 POST http://book.virginaustralia.com/Search.aspx - DIRECT/202.77.136.98 -

I am guessing the system is blocking 202.77.136.98 for somehow, but I don't think so.

The issue is that their site redirects the viewer based on their source IP to a local.
According to
TCP_MISS/502 you are getting a permanent error.

They may see too many requests from your proxy and are blacklisting you.
If your company personnel use their site to look up, you may want to contact them to see whether they can make an accommodation in your case.

It is not something that is inherently at issue with your squid configuration.

Though the line
1334531062.990  18020 192.168.8.3 TCP_MISS/000 0 POST http://book.virginaustralia.com/Search.aspx - DIRECT/202.77.136.98 - is peculiar since it has 0 for data being passed and no indication on the status which 000 is not common for a post a get request is a different matter.
