What steps will reproduce the problem?
1. Make a post request with http.Client
2. If a 30x is returned, the redirect isn't followed

http.Client should follow the redirect chain, and return the final response

Which compiler are you using (5g, 6g, 8g, gccgo)?
8g

Which operating system are you using?
Windows 386

Which version are you using?  (run 'go version')
devel (straight from hg)

Redirecting after a POST is a common idiom, see

Yes. post-redirect-get is a very common webapp server pattern. A best-practices one,
arguably.
Annoying to have to build your own redirecting Post implementation out of lower level
methods.
