Bug #: 53104
Summary: LogFormat "%{xyz}C" truncates cookie content at '='
character
Product: Apache httpd-2
Version: 2.2.22
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: mod_log_config
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
When using the '%{xyz}C' syntax to include the content of a specific named
cookie in a LogFormat definition, log lines describing requests in which the
cookie's content contains an '=' (equals sign) character will truncate the
printed cookie content at the first '=' character. A conversation with sfritsch
on #httpd-dev suggests that this may have cropped up as an unintended
consequence of changes that were made to resolve PR 28037. Details follow;
please let me know if there's anything else I can do to help clarify this
issue.
