hi all,
can somebody explain me need of having getPathInfo() method in the HttpServletRequest object?
from the API i get that it is to get cgi variable PATH_INFO but then why we need PATH_INFO variable if we can achieve the same effect using parameters you know...
what i am missing?
is it the case that PATH_INFO was the earlier support before the support to parameters in the URL and now to maintain backword compatibiltiy servers support PATH_INFO variable?
please help me.

i am realizing something.
PATH_INFO variable is used to form a value for PATH_TRANSLATED variable by the "web server" to get the physical path for the virtual path in PATH_INFO variable.
now as this is done by the web browser the application script is free of doing any processing and can directly access the PATH_TRANSLATED which makes the application script task little easier, right? so thats the purpose of having PATH_INFO instead embedding such information in the query string. if that information is in the query string then the application script needs to process it...
am i right in this derivation?
