Yes. I have written a subclass of LWP::UserAgent that
replicates Netscape's behavior (ie. it will follow POST
redirects but it will turn them into GETs before doing so).
A lot of web applications rely on this
non-standard behavior in browsers, making it a de-facto
standard, so I think it would
be a good idea to integrate such a class to LWP. I have just
posted the code for it here
By the way, overriding redirect_ok() to make UserAgent follow
POST redirects is not enough, because redirects won't be
converted into GETs, as browsers do.
More on the subject at Redirect after POST behavior in
LWP::UserAgent differs from Netscape's.
