Does CUPS support over the HTTP Proxy?

Solution Verified - Updated -

Environment

  • Red Hat Enterprise Linux 7
  • Red Hat Enterprise Linux 8
  • Red Hat Enterprise Linux 9
  • CUPS

Issue

  • How to configure the cups server communicate the printer over HTTP Proxy.
  • Does squid HTTP Proxy handles the CUPS IPP requests?
  • Can we configure the Squid HTTP Proxy between the cups server and the printer?

Resolution

  • Squid HTTP proxy only handles the HTTP requests.
  • IPP requests are different from HTTP requests and squid cannot handle them.
  • Instead, try configuring the CUPS server itself as a proxy server.
