[ruby-core:41657] [Ruby 1.8 - Bug #5764][Open] Net::HTTP should assume HTTP/0.9 on unexpected responses

[Mike Styer]

Issue #5764 has been reported by Mike Styer.

----------------------------------------
Bug #5764: Net::HTTP should assume HTTP/0.9 on unexpected responses
http://redmine.ruby-lang.org/issues/5764

Author: Mike Styer
Status: Open
Priority: Normal
Assignee: 
Category: lib
Target version: 
ruby -v: ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-darwin11.1.0] 


Currently Net::HTTP.read_status_line throws Net::HTTPBadResponse if the status line does not conform to HTTP/1.1 specifications.

But in cases when the web server implements a request size limit, it may not read HTTP/1.1 trailer after the request URI and may send back an HTTP/0.9 response.

Nginx does this for 414 Request-URI Too Large responses:

http://forum.nginx.org/read.php?2,52862,52862

Perl's Net::HTTP provides a "laxed" option to read_response_headers() to assume HTTP/0.9 if it can't find an HTTP/1.1 status line. Ruby should provide a similar option.

[ruby-core:93792] [Ruby master Feature#5764] Net::HTTP should assume HTTP/0.9 on unexpected responses

[merch-redmine]

Issue #5764 has been updated by jeremyevans0 (Jeremy Evans).

ruby -v deleted (ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-darwin11.1.0] )
Assignee set to naruse (Yui NARUSE)
Status changed from Open to Assigned
Project changed from Ruby 1.8 to Ruby master
Tracker changed from Bug to Feature

This appears to still be the case in master, but I think this is a feature request for a "laxed" option.  I'm not sure if we want to support such an option though.
