What about using the URL encoding example in the vlib application in the
examples apps. With this you can ...
Write your own url encoder which turns a url into parameters which are then
passed into an external page (see the IExternalPage interface).
The Friendly URL's section of the UserGuide is enough to get you started.
The only gotcha I found is that the example uses integer parameters which
parse to themselves, where I was trying to use strings. This means you have
to unsqueeze things. I posted my code for doing that to this list a few days
ago

Have you looked at Form Authentication?
I am doing something similar on my web site using basic authentication - I am
using apache (on my real web site - authenticating via url <location>
directives) or tomcat (in my test bed on my desktop) to validate the user via
standard basic authentication looking up the user in a database. The browser
then throws up a dialog box for login (which is why it wont work unmodified
for you) and logs the user in. You can then get at the data inside tapestry
to validate the user (with a PageValidateListener - which in the pageValidate
method checks the user
Here's an example of reading the user details and using it in the app.
@InjectObject("infrastructure:request")
public abstract WebRequest getRequest();
@InjectPage("ViewAccount")
public abstract ViewAccount getViewPage();
public void pageValidate (PageEvent event) {
String userName = getRequest().getRemoteUser();
if (!userName.equals(privUser)) {
ViewAccount viewPage = getViewPage();
/*
* Convert the username to have an uppercase first
character
*/
char ch = Character.toUpperCase(userName.charAt(0));
userName = ch + userName.substring(1);
viewPage.setAccountName(userName);
throw new PageRedirectException(viewPage);
}
