On the site experiencing this issue we are not capturing
browser information in the web server (Apache) logs, so I can't
answer your question. I don't believe the issue would be considered
weighty enough by those above me in my organization to allow
changing the log settings either.
I found one bug report since my last post that I thought
would be appropo, as apparently cfcache works in tandem with cfhttp
in the background:
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=95f66fd8
indicates
that intermittent connection issues between CFHTTP and CFMX
when CFMX is used in combination with Sun 1.3 and 1.4 JVM's. I
tried the recommended solution, however, and it didn't fix
anything. I am still in search of an answer. At this point I
receive one of these errors about every 4 days.
