Allow Upload of a file by extension

I am using a regular expression on the parameter I am pretty sure is the correct one, but I can still upload a file with pretty much any extension. Based on the documentation and at least one post from 2009, https://devcentral.f5.com/Default.as...aft=813995, I believe I am configuring things correctly but, I am not getting the desired results.

The file is posted as multipart form data.

-----------------------------41184676334

Content-Disposition: form-data; name="ICOrigFileName"; filename="Test.sql"

Content-Type: application/octet-stream

This is a test file. No SQL added.

-----------------------------41184676334--

Regular Expression has been enabled for the parameter "filename". My RegEx pattern is as follows: ([^\s]+(\.(doc|docx|txt|pdf|rtf|wps))$).

The .sql extension should be denied but it is not. I know I have missed something and would like some assistance. You help will be greatly appreciated.

Thanks,

TJF
