ports used by http protocol

Hi!

which are the ports used by http protocol? i have 80 and 8080 in this white space of setting... is there also the port 443 or not?how can i see which are the ports used by http protocol?

tnx for replyes =)

 

80 is the default port, 8080 is usually used for communication via a proxy server.

 

443 is used by https.

the above answers are correct - except to mention that a particular webserver can be setup to run on ANY port - that's the choice of the owner of the server - and it's as easy as changing 1 number in the webserver configuration, and then issuing the command to restart the server... which would make the ESET web access ineffective if change my webserver port to 10,000.

But you have real-time protection to pick up the slack..

 

Ports don't matter as long as a particular application is marked as a web browser. On Vista SP1 and newer, all applications are treated as if marked as web browsers due to Windows Filtering Platform that is used on these OS instead of traffic redirection via a local proxy.

 

that's good to hear... of course I have thousands of XP users still...

 

thank you very much... yes.. i've seen after for 443 ( used by https)
i've XP sp3...
thank you for your replies,perfect! =)
