Question

Here is the sample link that my page used to access database values

http://www.examlpe.com/product-line2/sales/'dynamic-value'

and Facebook authentication adds state and code at the end like this and cause an infinite loop of authentication

http://www.example.com/product-line2/sales/'dynamic-value'?state=foo&code=bar

This dynamic value is like lkji98. which is used by MySQL to get desired value from database. My question is how can i get back to the dynamic URL after Facebook authentication redirect

http://www.example.com/product-line2/sales/'dynamic-value'

My current .htaccess file is

Options -Multiviews
Options +FollowSymlinks
RewriteBase /product-line2/sales/
RewriteEngine on
RewriteRule   ^([1-9a-z]*)$ index.php\?u=$1 [L]

index.php is used to fetch result from database. If i put redirect url as index.php then it just redirect to index.php with state and code values

http://www.example.com/product-line2/sales/index.php?state=foo&code=bar

the facebook authentication works but dynamic url is lost.

Thank you.
