Referrals being blocked due to "Illegal File Type" violations

Hi,

we have web app that will begin receiving referrals. The referral ids can include a variety of characters including a full stop (.). At the moment, the asm policy treats anything after the last full stop (.) as a new file type. All requests will be similar to:

https://www.something.com/&siteid=blahblah.xhjkaaa.3432ff

We don't want to turn off the illegal file type checks as this is keeping a lot of noise out of the server logs eg. scanners looking for php. Is there a way that we can allow such URLs are https://www.something.com/&siteid=blahblah.xhjkaaa.3432ff to be loaded without flagging the illegal file type checks? They will all include "siteid"

Note, I did use a means of unblocking these requests in ASM however the business was not comfortable with the unblocking solution and would prefer to allow them through rather than blocking and unblocking.

Thank you.
