ASM - file type length on certain urls

i found the method to do this with url parameters, but that is not really what im looking for. there are request and POST data length restrictions on the file type which i want to lift on a file by file basis. this is also the safest in my opinion, allow little in general and make exceptions where needed.

 

 

had some time to try this in a test environment. changed from aspx to php, but the idea stays the same. i can configure a limit on POST data per file type, so php. but i can't configure it specifically for a certain php file / url, or is there a way to do this?
