cURL and LTM compression profile

Hello everyone,

I have a question about cURL, I have a Virtual server on LTM with a compression profil that works fine. When I'm using cURL to test I don't have compression statistics on the LTM, is it normal behaviour? Is the cURL going through the VS and the compression profile or is it a test to the backend that is not impacted at all by the VS configuration?

Thanks in advance for your help,
