Re: [users@httpd] mod_deflate: disable input filter for certain requests

[<hostalp@xxxxxxx>]

Hello,

thanks for the suggestion.

It looks like it could be generally doable, however as I understand it only output filters can be configured that way. There doesn't seem to be anything about input filters in the mod_filter docs. Or am I wrong? If yes how to use that approach with input filters then?

Best regards,

Petr
