When I invoke an URL I get in an infinite loop due to "301 Move Permanently" HTTP Response Code.

I'd like know the output and input requests that the machine is sending/receiving.

Is there any way to get this info?

The machine is a RHEL 5.5

tcpdump or wireshark would work for that – freedenizen Nov 21 '11 at 1:10

301 is moved permanently. 302 is found. Both are not errors but HTTP status codes that are used for redirects. – Dennis Nov 21 '11 at 3:56

I would suggest you to enable extended logs in the web service to log all input/output requests. Please check official mod_dumpio module documentation for Apache.

I can think of following two things you can take help of.

  1. httpd logs setup in your apache config, commonly found in /etc/httpd/logs

  2. tcpdump

tcpdump -vvvnn port 80 and host ip_addr_of_client -i any

where ip_addr_of_client is host from which you are accessing the url.
