How use BIG-IP to capture HTTP request and response

Hi gurus,   I want to use BIG-IP Virtual Server (with HTTP profile) and capture full HTTP request and response. Can I do that? We can not debug on the Client and the real Server. Thanks   Phong...

Hi,

I would use tcpdump with relevant filters and then open the capture in wireshark. To capture full packet use -s0 and to output to a file use -w filename.

$ tcpdump -nni 0.0:nnnp -s0 -w /root/capture.pcap host 1.2.3.4

The p modifier is useful for capturing end to end traffic. More here and here.
