Re: POST request loosing data with incomplete URL

Petr,

Not sure I fully understand what you're trying to do, but I use POST
operation in my application just fine.  Here's a snippet of PO code I use to
handle getting the parameters when using POST operations:

 HashMap parameters = new HashMap();

 public void run(HttpPresentationComms comms) throws Exception {

      Enumeration myparms = comms.request.getParameterNames();
      while (myparms.hasMoreElements()) {
           String pname = (String) myparms.nextElement();
           String[] pval = comms.request.getParameterValues(pname);
            try {
                parameters.put(pname,(String[])pval);
            } catch (Exception e) {
                msg("failed with exception: "+e);
            }
          }
<snip>

Then I get the individual parameters using either getParm(key) or
getParms(key) (depending on whether I expect more than one value).  Here are
these methods:

 protected String getParam(String key) {
      String[] items = (String[])parameters.get(key);
      if(items == null) {
           return null;
      }
      return items[0];
  }

 protected String[] getParams(String key) {
      return (String[])parameters.get(key);
 }

With regards to ServerPageRedirectException, I use them fairly extensively.
The only 'tricks' that I've found are (a) you can't change the Request, and
(b) you must usually pass the a modified path (set to, as I recall, the
value of your application root).

HTH,

Terry
