CF8 Multiserver IIS6-Jrun Broken Images

Question

Hello All
We have run into a problem with the multiserver install of
CF8 Enterprise Edition. I would appreciate any insight into it.
Server details:
Web Servers
IIS 6.0 on Windows 2003 Server
Use the JRun connector to communicate with CF servers (.cfm
.cfml .cfc .cfr mapped to jrun_iis6.dll)
CF 8 servers:
CF8.0.1 Enterprise edition; on windows 2003 server; 1 cluster
of 2 instances; running the proxy service on default ports (51000,
51002 and so on),
We want to use the reverse proxy for every type of file for
specific virtual directories on the Web server. This includes, .js,
.css, .gif, .jpg files.
Problem:
The coldfusion specific file formats are proxied to the CF
servers without a problem (since an IIS mapping exists for each of
them). However, for the static file formats it does not work
(broken images, missing .css files etc.)
We have observed that:
a) if there is no extension mapping on web server, IIS 6.0
sends a 404 message for the images on the page
b) if there is an extension mapping to the same jrun_iis6.dll
on the web server, we get a 503 error from the CF server
(Indicating no mapping on the CF server)
c) if in addition to (b), we introduce a url-pattern mapping
in web.xml, and associate it with CfmServlet, we start getting the
content of the image in a stream (Server response = 200 ) but with
incorrect content-type (it comes across as text/html). The images
still appear broken because the content-type is incorrect.
At this point, we are at a loss of what we are missing.
Has anyone run into this problem before... any pointers will
be much appreciated!
Regards
Kev

Very close. You need to map the extensions to the
FileServlet, not the
CfmServlet. Then restart CF and you are in business. You can
even remove
the mappings in IIS, the mappings in web.xml will overrule
them anyway.
