Status-Line without Reason-Phrase might add extra line feed.
Summary: Status-Line without Reason-Phrase might add extra line
feed.
Product: Apache httpd-1.3
Version: 1.3.26
Platform: Other
OS/Version: Linux
Status: NEW
Severity: Normal
Priority: Other
Component: mod_proxy
AssignedTo: bugs@httpd.apache.org
ReportedBy: puckman@taglab.com
On a ProxyPass if mod_proxy receives a response without a Reason-Phrase,
formatted like:
"HTTP/1.1 200 "
(The trailing space is important)
It will in this scenario return a header with an extra LF after the Status-Line
but before any headers.
My test scenario is a server running on port 1234 ProxyPassing everything to
port 80 where I have a mod_jk hooked up to a Coyote JK 2 to Tomcat 4.1.12.
(Coyote JK 2 is the one sending these kind of responses).
$ curl -s -i http://rhubarb:1234/index.jsp | head
HTTP/1.1 200

And for you hex junkies:
This is listening on the loopback interface on port 80. Notice the space after 200.

And this is the result from port 1234. Notice the extra 0a, where did it come from?
