As Cliff says, this is a redirect, not a subrequest.

Here's an example from the failure scenario.  We send the browser 302 from the 
POST and we then try to read the body of the POST request as the next request line.

[17/Oct/2003:12:13:25 -0400] "POST /servlet/Silly HTTP/1.1" 302 346
[17/Oct/2003:12:13:25 -0400] "-----------------------------7d32042f1603aa" 501 -
(If this were Mozilla, we'd also see the GET for the error document here.)

And with the patch, much more happiness.

[17/Oct/2003:12:20:09 -0400] "POST /servlet/Silly HTTP/1.1" 302 346
[17/Oct/2003:12:20:10 -0400] "GET /413.html HTTP/1.1" 200 23
