httpd, tomcat, mod_jk and LAST_MODIFIED

[shane doucette <do...@cs.usask.ca>]

Hello all,

I'm having a problem with a couple of my servers, whereby the last  
modified date of an shtml file isn't being properly reported by the  
LAST_MODIFIED variable, if server side includes are used in a  
directory that is served by mod_jk / tomcat.

So, to break down the run-on sentance...

I have servers, running httpd 2.0.55, tomcat 4.1.31, and mod_jk from  
tomcat_connectors 1.2.15.  I have several users that use the  
following code to report back the last modified date on their pages,  
using server-side includes:

	<!--#echo var="LAST_MODIFIED"-->

If I use server side includes on a page that is served by httpd,  
outside of a tomcat context, I get the proper response, i.e. the last  
modified date.  Here's an example:

	http://edjo.usask.ca/test.shtml

If I have the same page in a tomcat context, the last modified date  
is reported as

	Wednesday, 31-Dec-1969 18:00:00 CST

which I believe is the UNIX epoch.  This suggests that it's just  
getting '0' when it reads the last modified date.  Here's a  
corresponding example:

	http://edjo.usask.ca/classes/test.shtml

All other variables report properly.

I've hunted through the mailing list archives here with no luck,  
posted in other forums with no useful response, and Google hasn't  
been of any help at all.  I'm hoping that SOMEBODY has seen this  
problem, and has a workaround / fix.

On the example pages I've posted above, I've included information on  
my setup - my server software and the included modules.  I can also  
post appropriate configuration files if necessary.

Thanks for taking the time to read this.
