Question

Is there any light weight tools which can filter and output http headers/responses in human readable form? Something like wireshark. I have tried tcpdump; but it is hard to read.

Was it helpful?

Solution

If you able to configure proxy settings on the embedded device you can (like in web browser) you can be very flexible. I like for example Fiddler tool http://www.fiddler2.com/fiddler2/. If you start fiddler tool on you "normal" computer with Windows 7/XP etc, fiddler runs as a proxy with a port (typically 8888). If you configure on the embedded device IP address with this port as a proxy, you will see or be able generate auto-responses etc. inside of fiddler of your computer.

So you can solve the problem without installation on embedded device any software.

I don’t want to write a long text here, but I recommend watching video http://microsoftpdc.com/Sessions/CL25, where Fiddler developer Eric Lawrence explains Fiddler’s features.
