Why? Seems perfectly reasonable to me for a server to instruct a client not to cache virus definitions. Timely update is, after all, an important security consideration. Yes, it would increase the load on the server a bit, but since the client first checks MD5 and only asks for the full database if things have changed would it be that much of a problem? > >What values do you have for these environment variables (please note >that they are in lower case)? >http_proxy >no_proxy Both are undefined (unless I'm doing something wrong in trying to find out). Note my problem is with a TRANSPARENT proxy. I do not explicitly set up use of a proxy, it just sits there on my ISP's network and intercepts anything going out on port 80 (using a non-standard port does cut it out of the loop). -- Chris Hastie --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
