Subject: Preserving POST data on external redirect?
Hi all, my content handler does some work with POSTed data, and at the
end
wants to redirect to a totally unrelated server, preserving the POST data
that the client originally sent, so that the unrelated server can do its
own further processing with its own mod_perl, cgi, or whatever.
I can't get it to work, as I think I'm getting confused by some
pre-Apache::Request hints that I've seen for this. This is the mess I've
got so far (condensed):
sub handler
{
my $r = Apache::Request-new(shift);
... some calls to other subs here to do work ...
$r-method(POST);
$r-method_number(M_POST);
$r-headers_in-unset(Content-length);
$r-args($content);
$r-header_out('Location' = http://j.random.server.com/foo.cgi;);
$r-status(REDIRECT);
$r-send_http_header;
return REDIRECT;
}
It redirects, but doesn't pass the POST data. I thought it may have been
due to the original post data being deleted because I use it, so I tried
using Request-instance instead of Request-new, but that made no
difference either. Is it actually possible to do it if I'm using the
Request object?
Cheers

Re: Preserving POST data on external redirect?
Hi, yes that's one of the pages that I've been looking at, and the code is
almost identical (I've tried M_GET / GET as well). Still nothing
happening for me :-)

Re: Preserving POST data on external redirect?
A few things to note here...
You cannot post to a remote server in this fashion. You can take a POST
request to your server and convert it to a GET request to another server,
which may not be what you want.
To take POST content and POST it to another server you must proxy the request.
By proxy, I mean using LWP to make the request to the remote server via POST,
and delivering that returned content back to the user.
That's the easy part. Now you'll have to fix all the relative URLs within that
document so that they point to the remote server rather than to your server,
which is further complicated by things like CSS and Javascript.
Look into libwww-perl (LWP) and HTML::TreeBuilder (for fixing the links). I'm
sure that there is stuff in this lists' archives which go into more detail on
both of those...
Hope that helps,
Rob

Re: Preserving POST data on external redirect?
Hi,
The RFC 2068 (HTTP/1.1) specify that:
301 e 302 responses to POSTs shouldn't be redirected unless they can
be
confirm by user.
Also notes that some UA transform the POST to a GET, erroniously.

It can't, because this is the browsers job. Your script doesn't make a
connection the other server. You have to do transparent proxying or
depend on the browser.

Re: Preserving POST data on external redirect?
The link asks to change POST to GET. However, there is a limit on the length
of the URL so the POST data may be truncated and the redirect action may not
work properly.
Also, make sure to escapeURL() in the URL (which will also add extra chars
in the URL).
