Passing variables after url redirects to home page

Hello,

I am trying to send custom variables to a page that is not located on my Joomla CMS. It is a php page that is located in a subdirectory of my site. The Url structure winds up being:

www.mydomain.com/test2.php&custom+Event+Location%3D08086

When I send this to this page, it redirects me to my home page.

Do you have any idea how I can pass that custom variable onto that page without the system redirecting me home?

Because it should be:
www.mydomain.com/test2.php ?var1=something&var2=something_else
and not:
www.mydomain.com/test2.php &custom+Event+Location%3D08086
???
