Iwan,
I also call Spyce programmatically in addition to using it to serve up 
dynamic Web pages, so I appreciate where you're coming from. However, I 
don't actually get what you're trying to do. Are you saying that some 
of your errors are recoverable and that you'd like to ignore them and 
have Spyce continue processing?

My code for handling errors generated programmatically gets some detail 
about the error, records that data and then dumps processing to an 
"oops.html" file which basically says "Sorry, something went wrong". I 
understand that you don't want the output page, so couldn't you just 
use the same technique to execute whatever code you want and make 
oops.html a zero-byte file?

Sorry that I'm not getting it! =)  Maybe a high level example of what 
you'd like to be able to do would help.

bye
Philip
