ASM restrict upload larger than long_request_buffer_size

OK, so first of all this depends on what you are trying to achieve. I assume you want to allow large uploads for a specific URL/policy? e.g. "/upload" while preserving the global "long_request_buffer_size" limit.

In this case you can disable ASM for that specific URL using iRule as described here:

If you are running ASM v11.5.0 and higher you no longer need to disable ASM as the first 10Kb of the request will always be processed, see solution SOL17573:

Hope this helps,
