Quick Header function

Always leave a space after Location: in order to stick to the HTTP specs and avoid possible problems with some browsers

In addition to the above, make sure that the header function gets called before any output is sent to the browser.... unless you are using output buffering (via the function ob_start().. in which case at the very end of the script or at some point you'll have to flush out the buffer using the function ob_flush() at which point the buffered output actually gets displayed in the browser).

also, the location header isnt the only one that you can use..... other types that are commonly used are ...

Last-Modified:

this will indicate the last time the document was changed on the server.

You can also use the cache control header.. to tell the browser how to cache a page, like this:


here we request the browser not to cache the page at all.

there are many other types.. and you can find more details on php.net ... just search around or download the php manual.....
