ASM restrict upload larger than long_request_buffer_size

Is it possible to restrict an upload to a value (e.g. 25MB), which is larger than the long_request_buffer_size? I don't want to touch the long_request_buffer_size variable as it has global impact, bu...

Hi Sam,

 

I'm aware of the possibility to use an iRule to disable ASM on a specific URL, but that's not my intention. My intention was to still use ASM and allow uploads up to e.g. 25MB, but blocking those which are larger than that.

 

But this seems to be not possible at all, right?

 

But looking at the mentioned solution, does this mean I need to disable blocking-mode for "Request length exceeds defined buffer size" at all if I need to pass large uploads though ASM? But disabling this violation still investigates the first 10KB for any other violations if the request is larger than the "long_request_buffer_size"?

 

So at the end the required upload restriction needs to be configured on the webserver, right?

 

Thank you!

 

Ciao Stefan :)
