Subject Re: request.getparamter doesn't return anything without an '=' (equals) in the query string
Date Thu, 10 May 2001 16:55:46 GMT
It's my belief that iPlanet is not parsing this correctly.

The specification does not give details on the expected syntax, but it is
interesting to note that the HttpUtils.parseQueryString() method requires
name=value pairs in order to parse request parameters.  The same format is
used to parse data from the input stream on a POST request.

If you just want the part of the request that follows the "?" character,
and don't need it parsed to request parameters, you can simply call:

  String value = request.getQueryString();

instead.
