Doubt on "dispatcher" element in "filter-mapping"

[H Pathak]

1. In filter-mapping, if no dispatcher element is specified, then by default, the dispatcher element is "request" (since the filter gets called during the client request)

If we change the mapping to set

  <dispatcher>INCLUDE</dispatcher>  

, does this mean that the filter will be called only on include action (from another servlet or jsp), or will it also be called on a client request?

[H Pathak]

folks, any idea?

[Saurabh Kumar]

<dispatcher>INCLUDE</dispatcher>

With this, the filter will be called only on include().

Thanks and regards,
Saurabh

Saurabh is correct.

REQUEST is the default if no dispatcher tags are given, but if you specify a dispatcher tag and still want REQUEST in the mix, you'll need to explicity add REQUEST as a dispatcher tag value as well.
