header() function question

bnownlater

I am new to php. I am trying to convert my asp pages to php. I am trying to set these on a PAGE by PAGE basis (not for my whole web site).

I am trying find the equivalent PHP code for the following ASP code:

//Every user's session information will remain in memory on the web server until 120 minutes after the user's last request or if the user refreshes a page.

Session.Timeout = 120

//Specifies a date and time on which the content of the current page will cease being cached on the client machine.

Response.expiresAbsolute = Now() - 10

//This prevents the client's browser from caching the page

Response.expires = 0

//Allows you to add your own HTTP response header with a corresponding value.

Response.addHeader "pragma", "no - cache"
Response.addHeader "cache-control", "private"

//Sets the amount of time before the script times out to 200 seconds.If the script takes more than 200 seconds, the script will time out and a time out error will be sent to the client.

Server.ScriptTimeout = 200

Should I be using the header function to set these on a PAGE BY PAGE basis? I saw the example in the PHP manual , but I am looking for a better explanation of the header(). Thanks.

You can use the function to send the pragma and the cache-control.

something like

<?php

// first create a session or recover the current one.
session_start();
// set the timeout to 120 minutes.
session_set_cookie_params(60120);
// I think this is set in seconds so 60120 for 120 mins.

// set the script timeout to 200 seconds.
set_time_limit(200);

header("Pragma: No-Cache");
header("Cache-Control: Private");

<META HTTP-EQUIV="expires" CONTENT="Tue, 01 jan 1980 1:00:00 GMT">
<HEAD>
</HEAD>
<BODY>
Blah.. blah.. blah

</BODY>

I think that covers everything.

Thanks for the insight Mark.

I did alot of footwork and found that using meta tags is not the best way. I did find that using the header("Expire: ...") is better. Thanks for the info.
