Re: Entity Enclosing Requests

[Melvin Mah <me...@yahoo.com>]

Hi Oleg,

I just referred back to LoginDemo - one of the samples
for HTTPClient - to test the Redirect and changed a
little using some parameters for the site Engineering
Village.

Now that the login status is successful, I want to
entering a key term and then EV will redirect to
another page and send me the results based on the
keyword I would enter.

Currently, the pointer link is at
/Servlet/Controller/CID?=quicksearch&database=1.
(after login)

The link shown after the search results are returned
would be at: 

The question is can I just simply reuse the last half
of PostMethod in LoginDemo (modified) and just adding
new NameValuePair variables? Do I have to modify
anything substantially?

Thanks

That totally depends on the server application. You should
first try to make it as simple as possible. If that doesn't
work, the primer explains how to proceed:
