redirect POSTs bigger than 1MB

This rule works with IE6 but not with Mozilla based browsers. Why is that ?

 

 

The client shows a alert "The document contains no data"

 

 

The rule is:

 

 

when HTTP_REQUEST {

 

if { [HTTP::uri] starts_with "/upload" } {

 

set method [HTTP::method]

 

set clen [HTTP::header Content-Length]

 

if { $method =="POST" and $clen > 40960 } {

 

log local0. "Over 40 kb post: ($clen) from [IP::client_addr]"

 

reject

 

HTTP::respond 307 "Location" "http://www.mydomain.com/xxx.html"

 

}

 

}

 

}

 

 

I have tried to add HTTP::close before HTTP::respond, but it doesn't effect anyway.

 

 

I also tried to change HTTP::respond line to

 

HTTP::respond 303 content "http://www.mydomain.com/xxx.html"

 

and it doesn't effect either.
