Hi "Jltaylor",
How are you doing? Find I hope. I had meant to e-mail before now,I'm sorry that I haven't yet.
As to the problem that you are having, I think that Jor is right. There has to be something that is being filtered that the "Bess-Proxy" needs in order to work right. And I think that the "User-Agents" is a good canidate for it. If the Proxy works right with I.E. browser, then you could disable the User-Agent Filters altogether and your real Browser/OS should be forwarded to the Proxy, and if it Filters out the un-desirable sites, then it is the User-Agent.
Here is a Filter that you can use:
--------Start Filter-------
Key="User-Agent:(out)Bess/Proxy"
Match="*"
Replacement="Mozilla/4.0(compatible;MSIE 6.0;Windows NT.5.1; FOC2001)"
-------End Filter-------
Just right click on Proxo Icon>Headers>New>and then 'copy & paste' the Values in the correct lines, click Ok, and the 'tick' The filter inorder to enable it. This should be what the sites see as your User-Agent, "Including the Bess Proxy". If you are using a User-agent Rotation Filters, just let me know and we can set your Proxo up to Rotated U/A on every other site but use the one above for the Bess-Proxy Only. (VERY IMPORTANT! The " " in the Filter Values are NOT part of the Filter, they only show where the Filter Values start and where they stop, so leave them Out of the Filter.)
I hope that you have a Wonderful & Blessed Day, My FREIND! Please let me know how you come out on this problem.
