When I started writing the SSI-servlet I did not have in mind to
add support for ".jhtml", I was envisioning a servlet that _only_ supported
NCSA SSI. I believe that SSI support and ".jhtml" support are two different
packages so therefore when I looked at JSSI I did it from a view of how easy
it was to modify this to work with Tomcat, for me and write up the missing SSI commands
and also "strip out" the ".jhtml" support since I believe that that's another
package/servlet/"whatever" to be implemented. Both so that it leaves the user
with most flexibility as well as making it easier for us to maintain/update/modify
without breaking the other functionality. I came to the conclusion that it was
probably easier for me to try to use what JSSI has done in terms of SSI commands
and implement that in "my" framework than it was for me to port the whole
application. By the way, I just implemented Expiration and buffering.

My goal is to stick to the NCSA SSI standard and maybe later on add support for xSSI
so I don't think that _anyone_ will have problem with the SSI implementation from a
user perspective.

I'm not trying the reinvent the wheel, I just want to accomplish a robust SSI-package
that does only that and does it good. I haven't looked at ".jhtml" and hadn't even
planned
to write up that support for tomcat. But if my spare time allows me maybe I should :)
Anyone can feel free to comment since I'm more than willing to discuss and eventually
change
my mind in this matter for the best of the outcome.
