psymonic Posted November 7, 2008 Share Posted November 7, 2008 Hi all im new to this board, hopefully you will be able to help me out here. My question is what exactly does post-check and pre-check do, I used to know this but i forgot and was stupid enough to not comment my code. If anyone has a definite answer ill be thrilled to hear it because endless searchs on google just couldnt help me out this time.

psymonic Posted November 7, 2008 Author Share Posted November 7, 2008 Thanks for replying thorpe, most sites dont use post-check or pre-check. Here is a site which mentions them but doesn't use them. http://www.computec.ch/projekte/httprecon/?s=database&t=head_existing&f=cache-control I think when post-check is set to 0 when you submit a form and then click back you are asked if you want to resubmit the form but when its set to 1 and you submit a form and click back, you go back to the previous page without the form being re submitted. regards I was either post-check or pre-check which does that but i think it was post-check, either way i cant remember at all what the other one does.

psymonic Posted November 10, 2008 Author Share Posted November 10, 2008 It seems no one has, however i have a zend study guide and its used it there however it just says its use for caching, but it doesnt say what. Here in a IE blog they are talking about it. http://blogs.msdn.com/ie/archive/2006/06/01/613132.aspx Also can someone please tell me what setting public and private do in cache-control headers.

psymonic Posted November 10, 2008 Author Share Posted November 10, 2008 Its not code its a HTTP Resonce from servers, take this very thread for example i got this responce HTTP/1.x 200 OK Date: Mon, 10 Nov 2008 16:42:35 GMT Server: Apache/2.2.8 (EL) Expires: Mon, 26 Jul 1997 05:00:00 GMT Cache-Control: private Pragma: no-cache Last-Modified: Mon, 10 Nov 2008 16:42:35 GMT Content-Encoding: gzip Vary: Accept-Encoding Keep-Alive: timeout=2, max=100 Connection: Keep-Alive Transfer-Encoding: chunked Content-Type: text/html; charset=ISO-8859-1 im asking what the "private" means in: Cache-Control: private and what would happen if you replace private with public to give: Cache-Control: public also I still need to know what: Cache-Control: post-check: 1, pre-check:1 would do.

premiso Posted November 10, 2008 Share Posted November 10, 2008 Not sure what the private vs public is. I am sure that post-check=1 is that after the page has posted it will check for a new version, where as pre-check=1 the moment you load up that page it checks for a new version. I am not 100% on it, but that makes the most logical sense.

psymonic Posted November 10, 2008 Author Share Posted November 10, 2008 post-check=1 is that after the page has posted it will check for a new version by posted do u mean a form submitted and i though no-cache made it look for a new version of a page. pre-check=1 the moment you load up that page it checks for a new version. whats the point in looking for a new version if the page already has been loaded. This is really confusing. But thanks for your reply.
