The default attribute has a default value of no. If set to yes, the Sottoprocessi Arbortext PE can service any HTTP request. If any TestSet elements are defined for this Sottoprocesso Arbortext PE pool, they are ignored.

As described in Sottoprocesso Arbortext PE Allocation, when a request handler calls E3RequestContext.allocateE3Subprocess, it passes the current HTTP request. The Arbortext Publishing Engine Request Context passes the HTTP request to each Sottoprocesso Arbortext PE pool defined in e3config.xml, asking whether it can fulfill the request. The Sottoprocesso Arbortext PE pool with default set to yes always responds that it can service the request.

Be sure to give only one Sottoprocesso Arbortext PE pool the yes value for the default attribute. The pools are queried in the order they're configured in e3config.xml, so make sure it's the last pool configured in the SubprocessPools section of e3config.xml. Because the default pool handles all HTTP requests, any pool configured after it will never be asked to handle a request.
