Trying to change compression on a options method is useless.

 

Compression only applies to content, not to headers.

 

Options method doesn’t expect any content, so there is no compression applied.

  • virtual server is configured with profiles. If no policy or irule change it, the profile is applied to vs.

  • all irules assigned on a vs are evaluated even if a policy rule matches before on the same event.
