Apr 17, 2018 · Pragma: no-cache prevents caching only when used over a secure connection. A Pragma: no-cache META tag is treated identically to Expires: -1 if used in a non-secure page. The page will be cached but marked as immediately expired. Cache-Control META HTTP-EQUIV tags are ignored and have no effect in Internet Explorer versions 4 or 5.

In this last situation, no matter what Pragma or Cache-Control your server sends, the proxy might decide to override and modify your directives when the proxy forwards the response to the browser. The other argument foisted upon us to use Pragma is that not all proxy servers support HTTP/1.1.

Note: Pragma is not specified for HTTP responses and is therefore not a reliable replacement for the general HTTP/1.1 Cache-Control header, although it does behave the same as Cache-Control: no-cache, if the Cache-Control header field is omitted in a request. Use Pragma only for backwards compatibility with HTTP/1.0 clients.

The HEAD loads and the Pragma comes into play. The browser gets the go ahead to not cache the page, however there is not yet a page to not cache. How's that for backwards logic? Since the page hasn't filled the 64K buffer, there's no page so the Pragma is ignored. Thus...the page is cached. The solution is to play to the buffer.

I read about Pragma header on Wikipedia which says: "The Pragma: no-cache header field is an HTTP/1.0 header intended for use in requests. It is a means for the browser to tell the server and any intermediate caches that it wants a fresh version of the resource, not for the server to tell the browser not to cache the resource.

Jun 26, 2017 · The only setting for pragma is no-cache. Cache-control has more directives to set for flexibility. Max-age and revalidation are two directives that can be set. The browser will have to stick to those settings. The recommendation I’ve seen is to set pragma with no-cache and cache-control with no-cache, no-store, must-revalidate, and private.
