Since I am new to PHP, I need the help of someone who is very familiar with
the way PHP handles the setting of cookies and page redirection - in other
words, an expert!
Here is an outline of the problem:
1) client browser hits myPage.php
2) myPage.php does a few checks & recognises that this is a first visit
3) myPage.php sets a cookie using setCookie()
basic browser detection
5) checkBrow.php does checks and looks for cookie written by myPage.php
6) checkBrow.php fails to find the cookie because header( "Location:
http://someaddress" ) in step (4) has trashed the header containing the
cookie information!! Note that ob_start() has to be used to prevent any data
being sent to the client before the header has been set.. i.e. the page is
being cached server-side.
myPage.php was originally written in ASP and worked fine. ASP seems to write
the cookie back to the client browser first, and *then* performs a redirect.
PHP on the otherhand seems to overwrite any existing headers when using
header( "Location: http://someaddress" ) because they are cached. While this
behaviour seems obvious it presents some rather annoying problems. I've
kludged a fix by setting the cookie and then writing a page that uses a
<META> refresh to redirect...
Is there a more elegant way of doing this?? Please please tell me there is
because I hate having to do such a crappy workaround. If you need more info
on what the html headers look like - before and after - mail me and I'll be
happy to provide you with them...
