What is the proper way to tell the browser not to cache?
browser, caching, meta-tags
Solution
Send your expires headers using your server. Specifically, if you're using apache, look at this:
http://httpd.apache.org/docs/2.0/mod/mod_expires.html
Problem
I have a web page that always needs to stay current. I do not want the browser to cache it. To that end, this meta tag is embedded with the page: ``` <meta name="Expires" content="Tue, 01 Jun 1999 19:58:02 GMT"> ``` However, some browsers seem to ignore it. Chrome is particularly bad at it, though other browsers tend to do the same thing. When I pick the page from the bookmarks bar, most of the time, it doesn't even hit the server, just loads it from cache. If I then press F5, it does go to the server and fetch a new copy. Am I missing something simple? I thought the expires meta tag is the way it's done. This is happening on an IIS 5.0 on Windows 2000. Bottom line: looks like meta tags inside the HTML code pretty much do nothing. However, setting the expires tags within the HTTP does the trick nicely.
