I downloaded the source from here if anyone's interested: http://helpx.adobe.com/coldfusion/kb/rhel-connector-configuration.html. Do you know what the difference is between the ASF version and theirs? IMHO it should work if you use the ASF version directly. I can't see a reason for them to have their own (separate) source. I'd like to avoid using their custom version as I don't know how it will play if other non-ColdFusion based apps want to use AJP in the future. The tech you use for your web application is not relevant: AJP is just a binary HTTP-forwarding protocol. Theoretically, there should be nothing about the web application that would require something specific (and extra) to be supported by CF or anything else. Does anyone have any recommendations on how I might be able to figure out what was changed? I'm not a developer so I don't know much at the code level. You could use diff -r against the Adobe code in one directory and the ASF code in another. I'm not going to download it all and pour through it, but you can easily do so. Make sure to use a diff argument that ignores whitespace.

This does not look like a problem with CF, since you are serving a .html file (right?). This looks like some corrupted messages. It could be a bug introduced by Adobe, some network problem, etc. I did a Google search on Unknown AJP protocol code: 0F and there's some concern that you might have mismatched max_packet_size. Can you check these between httpd and Tomcat?

Re: ColdFusion10 custom mod_jk difference
I completely agree with you, but unfortunately am stuck with CF as the developers won't switch and the company already made an investment in licenses. On Tue, Apr 8, 2014 at 3:08 PM, john Matlock johndmatl...@gmail.com wrote: Recommendation: Switch away from Adobe CF 10 to Railo (www.getrailo.org)
