[xsl] Increase Doc-available timeout?

["Angela Williams" <Angela.Williams@xxxxxxxxxxxxxxxxxx>]

Is there a way to increase the timeout length before the doc-available
function returns false? The url I am using is to a servlet that will
return a document when I enter the url in the browser, but it takes a
few seconds to return.  Doc-available is always returning false.

Are there any other options?
