[squid-users] websocket with sslbump

[Eliezer Croitoru]

Hey Niels,

 

I can help you with this if you need.
I have a pre-compiled version and while it’s not a Debian packaged ie .deb file it’s a matter of unpacking the files into the FS.

Also take a peek at the docker build:

Let me know if you need this binaries, I can put them at:

Hi Alex,

 

Thank you for your response. I’ll be opening up a Bugzilla ticket for opaque messages through ICAP if it doesn’t exist already.

Related to the squid 5.x, I’ve reached out to the debian package maintainer last week for a binary install in the repos but no response as of yet.

 

Best regards,
Niels Hofmans

During testing sslbump + icap I noticed that websockets (ws + was) are
not supported by squid. (Even if using on_unsupported_protocol)
Are there any plans for supporting this with sslbump?


Your question can be misinterpreted in many different ways. I will
answer the following related question instead:

Q: Are there any plans for Squid to send tunneled traffic through
adaptation services?

The ICAP and eCAP protocols cannot support opaque/messageless traffic
natively. Squid can be enhanced to wrap tunneled traffic into something
resembling HTTP messages so that it can be analyzed using adaptation
services (e.g., Squid applies similar wrapping to FTP traffic already).

I recall occasional requests for such a feature. I am not aware of
anybody working on that right now.

HTH,

Alex.
P.S. Latest Squids support forwarding websocket tunnels that use HTTP
Upgrade mechanism (see http_upgrade_request_protocols in v5
squid.conf.documented).
