User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 A webpage which contains cache-control directives is shown from cache instead of being reloaded. Directives used are: <head> <meta http-equiv="Cache-Control" content="no-store,no-cache,max-age=-1"> <meta http-equiv="Pragma" content="no-cache"> <meta http-equiv="Pragma" content="no-store"> <meta http-equiv="Expires" content="-1"> </head> The letter case of tags, directive names or values do not seem to have any affect on behaviour. On the positive side, Firefox reloads a page if "no-store" is returned in HTTP response header. AFAIK, browsers are not required to process http-equiv tags, but many developers rely on this behaviour. MSIE understands them, including cache-control tags. MSIE 5.5 had a bug, the result of which was actual caching of the page, not intended to be cached. I found about it here: http://www.htmlgoodies.com/beyond/nocache.html, apparently MSDN should more formal description. On another note, I used two header tags on my page just like the author of the article (see link above) suggests, and Firefox shows two sets of directives in its Page Info/General/Meta table. Is this a bug? The directives have the same name, why two sets of them? Reproducible: Always Steps to Reproduce: 1. Put aforementioned tags on a page and load it. 2. Leave the page. 3. Return to the page using Back button, the page is not reloaded. Actual Results: Page is shown from cache Expected Results: Page should be reloaded from server

It doesn't work, either, if no-cache is specified in HTTP header.
