bug/issue payment processor blocked due to referrer filter

[nepravelniy]

I was trying to make an order on french website (got english language for your pleasure)

1. I have registered, added stuff to cart, added address and choose delivery method

2. last step was to enter my card to pay for the order and text fields was unavalible to type in

3. i disabled addons one by one to find that cleanurls is causing an issue

4. i enabled logging and found that some stuff was filtered due to ETag rule (i did not found any whitelist functionality so i disabled ETag filtering)

5. was still unable to type my card for payment, checked log again and saw that now referrer filter is blocking payment system

6. disabled filtering completely via popup menu slider and was able to make a purchase.

Can you fix that? It was hard to find because i have bunch of addons that could cause that issue and i was not even thinking that cleanurl can cause that before i started to switching everything off one by one and checking if website works. Can you add something like whitelist feature, so i can easily whitelist it and move on without waiting to rule update?

THANKS
