mod_jk 500 errors
Summary: mod_jk 500 errors
Product: Tomcat 4
Version: 4.1.24
Platform: All
OS/Version: All
Status: NEW
Severity: Enhancement
Priority: Other
Component: Connector:JK/AJP (deprecated)
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: james@squish.net
Enclosed is a patch for mod_jk to give Apache 1.3 an additional string for
displaying in standard 500 error messages when Tomcat cannot be contacted.
I'm certain that the function below could be used in mod_jk2 and that Apache 2
can't be much different.
The message reads "The mod_jk connector was unable handle the request for
<URI>. This may mean an application server could not be contacted to service
this request. Please try again later."
This is much better than the average "internal server error", especially for
system administrators who have to administer other user's Tomcat instances.
