Subject Re: Passing HttpClient Header back to the browser
Date Fri, 02 Jan 2004 15:10:07 GMT
Hi Thad,

The problem has nothing to do with Struts or HttpClient I believe.  It 
is because a cookie is required to access the site.  Since there is no 
way to set cookies on the browser from an applet, the cookie must be 
set by the web server when the browser authenticates.  You would have 
the same problem when using the java URLConnection and some other web 
application framework.
