FusionReactor Technote - FRS-231

Due to an issue in the JRun version used with ColdFusion 9, the Hostname in Request URL's can sometimes contain the string "null" instead of the actual hostname.

Finished: 18:48:30.774 28-Sep-2009  200  192.168.0.11  11841  web-0  http://null:8500/test/test.cfm  0  Cur:(13%)67,809 Free:437,086

The problem occurs when a request is made against a port that is not the default port (e.g. 80) and the port number is not included in the HTTP Host header sent to the ColdFusion server by the web client. For example:

http://server.yourdomain.com:8500/test/test.cfm

Some web clients incorrectly do not include the port number in the Host: header that is sent for the request. For example:

GET /test/test.jdbcfast.cfm HTTP/1.1
Host: server.yourdomain.com
User-Agent: Mozilla/4.0 (compatible; MSIE 4.01; Windows 98)
Accept: */*
Accept-Encoding: gzip, deflate
Accept-Language: en-us
Connection: Close

This problem has been confirmed for Microsoft Web Application Stress (which does not send the port number in the Host header), but other clients may suffer from the same bug.

Workaround

To work around the issue you should use the default web port (e.g. 80), or use a different client that correctly sends the port number in the Host: header of HTTP requests.

A bug report has been submitted to Adobe for this issue.
