How to redirect a Joomla page to get validation externally Topic is solved

[emerote]

Hi there!

I need to redirect some pages of my joomla site to an external url where the user can validate and then be redirected back to the original joomla page with access to its content. The server that host the users login details is on a .asp environment.
They have provided me with the link to the validation page and apparently I need to make a page (ex. validation_ok.php) where I have to redirect the original page.

¿Can I place all the pages that need validation to get access to them on the same "validation_ok.php" file or do I need to make one single php file for each page? ¿What do I need to write on that php file?

Sorry about all this questions, but I´m totally stuck on this matter. Does anyone know how to do this? Any help on this would be highly appreciated!
