NimbostratusSize after compression
Hi,
I use iRule for sending Logs to external component.
I want to get the size of the response after the F5 compression but unfortunately i get only the size before. i use the "content_length" head...

MVPHi Tomer,
you may take a look to the provided iRule posted in this topic...
https://devcentral.f5.com/questions/how-to-get-the-response-size-after-gzip-compression-49060?tag=irules
It uses the HTTP_REQUEST event to inspect the Content-Lenght before compression and the HTTP_RESPONSE_RELEASE event to inspect the Content-Lenght after compression and performs additional math to calculate the compression rate.
Note: Keep in mind, that HTTP responses with chunked HTTP content will not include a Content-Lenght header. It will be very hard to account the size for those requests... See https://en.wikipedia.org/wiki/Chunked_transfer_encoding for further information
Cheers, Kai
