Re: [squid-users] sqcwa meta http-equiv pragma no-cache and others

The faulty component is the web server (or webmaster) in this case.

<meta http-equiv..> headers is only valid if the web server hosting the
pages knows to parse the HTML and insert these headers into the HTTP
headers.

Unfortunately some web browsers stupidly enough also reads these
headers, making a mess of things (i.e. making webmasters think the
directives work when they infact do not...)

But more scripts of this type is always useful I think. If you make a
small web page that can act as a homepage for the script with some
description of usage etc then I can link to it from the "Related
Software" Squid page.
