Tomcat manager reload, start and stop functionality

Hi,

I have a question about some tasks of the manager app of Tomcat.

* The Reload-task doesn't stop and start the webapp, but I wonder how it
exactly works. Because when I am transferring a new jar-file on the server and
a Reload is run on the context, I need to know how this can affect the HTTP
requests entering that context at that exact moment the reload is "running". I
know we are talking about less than a sec. here in most cases, but imagine
thousands and thousands of SMS messages coming in via HTTP requests to that
context. How is this handled ? With timeout and try again ? Please explain this
if someone would be so kind ..

* The second question involves the same matter, but with the stop and start
task. The context is not active after running the stop (only for a very short
time but still) so any HTTP request will fail (I guess a 404 or something). Is
there a way to work around this ? Some kind of delay option or something.. to
tell that any HTTP request is put into a pool and then run again on the context
when it is active (after the start). Or are there better ways to assure nothing
gets "lost" .. (ps of course using jsp's ensures not needing the start and stop
, but suppose we're using servlets).

I looked it the tomcat docs, but there wasn't really an in-depth explanation
about this ..

Thx in advance :-)
