[BNM] apache ab -p and post file

[Jason Bailey]

Hello,

Not sure if anyone has used apache ab (benchmark) in anger to benchmark 
sites? Any other free (or free trial) stuff that I could try for https and 
form submission?

Has anyone got any examples of what to stick in the post-file (-p) option 
of ab to submit values to a form. Looks simple but not sure I'm getting it 
right

ab -n 100 -c -p post.txt

where post.txt contains
parameter1=value1&parameter2=value2

Is that it? Assuming I want to submit via post two variables/parameters?

I'm using webscarab to monitor the http traffic and what's coming back 
didn't look right; mind you it was nearly bed time.

Thanks
Jason
