jk connector and JPG files

[david wolf]

JkMount /test/*.jsp worker
JkMount /test/*.htm worker

I put the above line in the httpd conf file httpd.conf. The problem is
that if in the htm file it refer a picture, say some jpg files. If
these files have file extension as .jpg, the browser can correct render
it inside the html page. If these files have file extension as .JPG, I
mean, capitalized letters, the browser cannot render it inside the html
page (basically I got a blank rectangle inside the html page). What i
have to do to make it work is to put following line inside the
httpd.conf. (BTW, these JPG files are under the same dir as these htm
files)
JkMount /test/*.JPG worker.

For lower case jgp file extension .jpg, I do not even have to put a
corresponding line in the config file httpd.conf. These .JPG and .jpg
files are under the same dir.

Can someone explain to me, Why?

Thanks

David
