I don't think you're doing anything wrong -- the latter encoded url is
the one you want to use -- that is, you don't want to encode the '='s
that separate the name and value for each parameter pair. You should
only encode the parameter values, not the entire query string or URL
when creating the URL. The servlet engine has to read/parse the query
string and decode it to create the parameter name/value pairs -- but
it only decodes the values after it has separated the name and value.
So it needs to find the '='s in the encoded URL. Think about it. You
wouldn't be able to get an '=' in one of the parameter values if it
worked differently.
