NYCPHP Meetup

[Kristina Anderson]

Hi Paul,

As someone pointed out earlier this week, unless your app is set up so 
that the only entry point to it is a link from another URL, in most 
cases your user's entry point into your app would be typing the address 
directly, in which case there would not be an HTTP_REFERRER.

> Hi Chris ,

HTTP_REFERER

entered 
> "my" application.
> 
> In my INDEX.PHP,  I used an extra script named LOGIN.PHP, where the 
> HTTP_REFERER was captured.  Then in turn LOGIN.PHP called another 
script 
> named LOGON.PHP which picked up the HTTP_REFERER information. which 
in my 
> case is the url name of  my INDEX.PHP, Which of course pointed the 
way into 
> the application in the first place.
> 
> Within the application HTTP_REFERER works just fine. I can see its 
potential 
> and some importance possible uses within applications.

> I am guessing the way around my problem is to forget the use of 
HTTP_REFERER 
> and just put the user back to the login page and let the user press 
the back 
> button to let themselves out, or is there a more elegant way to do 
what I 
> want??
