Hello, I'm running squid 3.1.19 in tproxy mode, and I have some customers complaining that they have problem with stock exchange (share market) sites and software after implementing the squid. What I saw in the access.log for one of the customers is: 10.21.8.59 - - [04/Jul/2012:12:01:56 +0530] "GET http://login.angeltrade.com/AngeltradeDiet/DietOdinSingleInterface.asp?

What can I do to further investigate the case and probably resolve it... Any help would be appreciated. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/strange-problem-in-squid-with-certain-sites-and-strange-log-tp4655663.html Sent from the Squid - Users mailing list archive at Nabble.com.
