What's the purpose of the catch block in an ASM_REQUEST_BLOCKING scenario
We're returning custom ASM-error pages by using an irule whose initial structure follows the principle of the article ASM_REQUEST_BLOCKING. Some month ago i decided to remove the last block 'when HTTP_RESPONSE_RELEASE'. Today i temporarily re-added it and was quite surprised about the log entries. Although the irule works as expected, the content of the catch block is getting executed. How do i identify the typ of the exception thrown by the irule? And what action should it take in this case, since everything works fine?
