Could an app open on a webpage when a particular server requests a certain page???
Sorry, but you’ll have to give a little more information. Your question isn’t very clear.
If I build a application for a friends website and if i put a link to his website could there be a script for that application to open only when people click on the link from my site???
I can only think of 2 ways, neither of which is foolproof.
Use the HTTP referer header to test if they came from your page
- can be spoofed or not sent
Use a GET variable
- can be added to the URL and reused anytime
Thank you! How could it be done in PHP?
Basic stuff, just test for the SERVER and/or GET variables
if ( isset($_SERVER['HTTP_REFERER'])
&& ($_SERVER['HTTP_REFERER'] == 'my_site')
&& isset($_GET['my_var'])
&& ($_GET['my_var'] == 'my_var_val') )
{
showMyWidget();
}
Thanks a lot really helpful!
