Hi,
we're seeing a really weird problem in our production environment.
"Connection: Keep-Alive\r\n" is being pre-pended to the
RAW_POST_DATA, which makes requests error out. This bug is seen
infrequently and *seems* to be browser-related, although I can't
reproduce it using the browser reported in HTTP_USER_AGENT.
Set up is a hardware load balancer (NetScaler) -> mongrel_cluster
0.2.1/mongrel 1.0
Has anyone else seen this or have any advice? I'm thinking I'll
cobble together a kludge that inspects @head['RAW_POST_DATA'] and
just sub out "Connection: Keep-Alive\r\n", but I'd really like to
avoid doing that.
Here are two recent examples of the bug. Output is
@request.env.keys.sort.each { |key| puts key: @request.env
[key].to_s.strip }:
Parameters: {"ad"=>"5", "action"=>"new", "ct"=>nil,
"controller"=>"ad_keywords", "Connection: Keep-Alive\r\nad_keyword"=>
{"smart_keywords"=>"Non Emergency Transport \r\nNon Emergency
Transportation\r\nTransportation for Disabled\r\nTransport for
Disabled\r\nHandicap Transportation\r\nHandicap Transport\r
