Is there an equivalent to Internet Explorer's "network traffic capturing" in linux?

Basically I have a website which uses javascript to refresh the page at certain intervals. I would like to check whether the site refreshes and in what intervals.

Commandline or GUI tools are all fine.

Hi there,

I didn't know that there's something like that in IE ...

What browser are you using? For Firefox, I'd recommend the Live HTTP Headers extension, which logs all HTTP request and response headers being exchanged between browser and server. Opera has Dragonfly as its integrated developer tool, that should be able to do about the same. There may be a similar extension for Chrome, I'm not sure.

If you need something heavier, there's Wireshark, a network logger and analyzer. Wireshark is independent from any browser or other network application; it simply captures all communication on a selected network interface. If desired, you can filter that later. However, that may be a bit oversized for your needs.

Thanks. Live HTTP Headers (on iceweasel) works.
