(...) BTW, the reason I *had* to figure out how to do this is because after uploading a file, the server spits out a javascript redirect (this.replace ...) to the folder url the uploaded to. If that page was cached, the user would see the cached (...) (25 years ago, 9-Aug-00, to lugnet.publish, lugnet.off-topic.geek)

(...) EXPIRES (...) Just a clarification, my example was for direct writing of HTTP headers, as you must do in a CGI. I suppose those tags would work as META HTTP-EQUIV tags in a web page, but I'm not sure if all proxy caches look at http-equivs, (...)

(...) That's a keystroke, right? A process runs to generate these pages quite frequently. We want the user to see the most freshly generated page without the user having to take any action of their own. So we want to put tags into the page to tell (...)

(...) I read somewhere that not all proxy caches will observe this. Actually I think it said they only look at the actual headers, not HTTP-EQUIV. It doesn't hurt to cover all bases. See my other post for details. KL (25 years ago, 9-Aug-00, to lugnet.publish, lugnet.off-topic.geek)

(...) Here's what I do to guarantee no caching: void printCGIheader(){ printf("Content-type: text/html\n"); printf("Expires: 0\n"); printf("Cache-control: no-cache\n"); printf("Pragma: no-cache\n"); printf("\n"); } void printCookieHeader(char (...)
