[squid-users] TCP_MISS/403 353 HEAD text/plain Error help !!

[snakeeyes]

Hi Amos thanks for explanation

But the issue is it works fine from other paid proxies .

Again , the app is a link converter and it connect to proxy 
I will give u sample how app works :

It request link as below:
http://convertlink-bla-bla-bla.com/ytd/Youtube.class.php?url=https://www.youtube.com/watch?v=MYSVMgRr6pw&proxy=xxxx:yyyy


so the xxx:yyyy is the proxy ip:port

again 	Amos , since its outside squid and it works on other proxies , do u think we can do anything on our squid ?

any other ideas??

cheers

Your Squid is letting all of both types of traffic through, and it appears not to be caching the results.

That is good in a way. It means the problem is clearly something between the browser and Google servers, not Squid.

I can see several differences between the client requests. The working ones have a line or so more query parameters than the forbidden ones.
They are also consistently going to a different server (working *.12 , failing *.14).
