Ports & Protocols Google Chrome Supports

[malebolgia]

There's a chance Google Chrome/Firefox can become the default browser at the company I work for. However, I must first defeat the corporate policy. In submitting an application for use on the company network, you have to list all the ports & protocols used by the requested application. Seems more than fair.

I know a few ports & protocols supported in browsers (HTTP, HTTPS, FTP, SFTP), but I haven't found any documentation that lists all the other protocols & ports supported. This doesn't seem to be documented anywhere for any browser. Part of my brain is saying it's one of the OSI networking models. Any suggestions/documentation is appreciated.

Chrome also supports SPDY which is google's improved replacement for HTTP:

And like all browsers depends pretty heavily on DNS.

Looking at the source it also seems to support ocsp

As far ports as ports go, like all other broswers chrome will try outgoing connections on any port you specify. 80 for http and 443 for https are defaults but you can try whatever you want. Easily blocked by only allowing certain ports from workstation subnets.

@ekul Thanks, guess it's not practical to name all the ports & protocols that a browser uses. Best to to do a write up describing the common ports that will be allowed, and that everything else depends on the user's need & what the company firewall will allow/block.

Basically except for spdy it would be exactly the same as whatever browser you already use.
