On second read, can you elaborate on that one ?
Do I understand correctly, as follows ?

Originally, I have for the servlet a <url-pattern> like, for instance
<url-pattern>*.xyz</url-pattern>

and I have for filter B (the one to disable) a
<servlet-name>servletX</servlet-name>

I would
a) replace this last by a <url-pattern>*.xyz</url-pattern>

b) make filter A, in case it doesn't want filter B to run, change the 
request URL to, e.g., "something.abc", so that filter B does not run 
anymore.

c) change the servlet def. so that it handles url-patterns "*.abc" AND 
"*.xyz".

Yes ?

If that works, that's a clever idea, which seems not too difficult to 
implement, even for me.
