RE: [PHP-DB] No Caching (Reloading Fresh Content)
Thanks, but I think you already sent me that link. Or maybe it was a different Chris. Either way, I couldn't get any viable answers from there. - Jonathan -Original Message- From: Boget, Chris [mailto:[EMAIL PROTECTED]] Sent: Tuesday, November 13, 2001 1:30 PM To: 'Jonathan Hilgeman'; [EMAIL PROTECTED] Subject: RE: [PHP-DB] No Caching (Reloading Fresh Content) How can I ensure that a specific page is never cached and ALWAYS gets processed every time it is viewed?

Re: [PHP-DB] No Caching (Reloading Fresh Content)
I read a bit of it, but it's still giving me trouble. I have the following short, test, PHP script: ? Header(Cache-control: private, no-cache); Header(Expires: Mon, 26 Jul 1997 05:00:00 GMT); # Past date Header(Pragma: no-cache); $link = mysql_connect(localhost,root,password); $R = mysql_db_query(database,SELECT uid FROM users LIMIT 200); $N = mysql_num_rows($R); ? FORM ACTION='?=$PHP_SELF;?' METHOD='POST' Number of Users: ? print $N . - $Step; ? INPUT TYPE='Hidden' NAME='Step' VALUE='? print $Step+1; ?' INPUT TYPE='Submit' /FORM Now, I load that script up, which displays Number of Users: and a submit button. I click on the submit button, and then again on the next page and I basically see: Number of Users: 200 - 3 and a submit button. Now, keeping the browser window open in the background, I go and edit the script, changing LIMIT 200 to LIMIT 100 so that it will return just 100 users. I save and then go back to my browser and click the Back button, but now I get an IE message saying that it cannot automatically resubmit the posted information. What I want is to have it re-query the database with this new LIMIT 100 query and return Number of Users: 100 - 2 So at this point I have either the option of forcing the user to see the IE page and have them reload it, which works, or by allowing caching to go on. Any more thoughts? - Jonathan Chris Boget [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...
