I have set up a Squid reverse proxy server for a web site named http://www.dajiyuan.com This site is ok both for IE and Netscape browsers. But when I reverse proxy it, it pop up a message says "A license is required for all but for personal use of this code. See terms of use of Dyn-web.com". After I click OK, many image .gif files can not display. In the access_log, it says TCP_MISS 302 678 .... First_UP_Parent. I cannot understand why Squid did not cache this images since they can be catched in regular browsers. Thanks a lot! Fulan Peng.
