Cookie variable in Apache LogFormat outputs incorrect value

[Richard Mitchell]

Given the example request:
{{{
GET / HTTP/1.1
Host: example.com
Cookie: __foo_bar="baz"; __foo="quux
"
}}}

and the Apache configuration:
{{{
    LogFormat "\"%r\" %>s \"%{__foo}C\" \"%{__foo_bar}C\"" mylogformat
    CustomLog /path/to/log mylogformat
}}}

Then the relevant entry in /path/to/log will be:
{{{
"GET / HTTP/1.1" 200 "bar=\"baz\"" "\"baz\""
}}}
when it ought to read:
{{{
"GET / HTTP/1.1" 200 "\"quux\"" "\"baz\""
}}}

{{{
$ apache2 -v
Server version: Apache/2.2.12 (Ubuntu)
Server built: Nov 18 2010 21:16:51
}}}

(Ignore the newline after 'quux' in the example request)

Appears to be the same as this upstream bug: https://issues.apache.org/bugzilla/show_bug.cgi?id=28037

This was fixed in Apache v2.2.17, which was included in Ubuntu 11.04. This bug affects lucid and maverick.

Thank you for taking the time to create a detailed bug report. In the future, some using 'ubuntu-bug apache2' would collect some other information that might be helpful to developers looking to find a fix. In this case, it would have included release information.

And just as a warning, I would guess by your 'apache -v' output that you're running karmic (9.10) which is no longer supported. You should upgrade to lucid to continue to receive security updates.

maverick has seen the end of its life and is no longer receiving any updates. Marking the maverick task for this ticket as "Won't Fix".
