Summary: Efficient Page Refresh w/o restart (ala jsp)

Initial Comment:

I would like to drop new pages into production without 
having to restart the webserver. This exists in 
development as an option, but is expensive (reloads 
pages every click).

This would need to be efficient like JSP. That is, simply 
check the timestamps on the files to determine whether 
they are updated. If they are, then reload, w/o flushing 
any sessions. If the files are in a .zip (ie. .war file), then 
no updating/checking is necessary.

This should be the default. No option necessary, 
development or production. If you don't need it, .war it.

This is highly important and practical for a 24x7 website.

Joel

Could you extend the page service to check the timestamps 
and have it call the reset service if needed?

I suppose having your own 
custom "AutoRefreshPageService" would be somewhat 
difficult though because so many things would still call the 
baseclass..

Is there any merit to this? Something I am missing?

This is a lot of work.  It may be possible in the future, but 
there are more important priorities right now.

I woudl suggest looking at the reset service; it;'s job is to 
discard all cached data.  It is disabled by default because it 
seems like a likely candidate for a denial-of-service attack.

Perhaps you could create a variation of reset that had some 
app-specific validations (i.e., that the client originated within 
your internet domain).  Thus, after uploading new content, 
you could invoke the service to force Tapestry to accept the 
changes.
