Subject Re: Error 404: file not found while using BASIC HTTP Authorization
Date Fri, 19 Jan 2007 20:07:22 GMT
Hi,

We also tried another thing. Our *web.xml* was for a Struts application, 
so we had following tags in it.

   <taglib>
    <taglib-uri>/tags/struts-html</taglib-uri>
    <taglib-location>/WEB-INF/struts-html.tld</taglib-location>
  </taglib>

We commented out all such tags and the application worked fine i.e. it 
prompted us for the login and we were able to see *about.html*.
 
But for our struts application we need these *taglib *tags. So, does it 
mean, this BASIC authentication is not compatible with struts? Or is 
there some alternative way of specifying things for Struts.

Pls advise.

Thanks and Regards,
Shilpa
