++ JavaServer Pages (JSP) FAQ:

How can I get the complete URL address
(like "" (with or without "http://")) from a HttpServletRequest?

Is there any justification in creating a cache that maintains values pulled from a given property
file so that your app does not have to continually getProperty() on the same property over
and over again?
I suppose the key question is: How much of a performance hit is it to access a property file
as opposed to maintaining a cache (HashMap) of key / value pairs?

Can someone explain to me what this code does and what situations it needs to used?
