[Mono-list] Webservise Discovery Language

[Ben Clewett]

Kornél,

I am making progress.  You code seems to work well, I've just got to 
tidy it a bit.

You asked me to report a bug if a change in the Web.config is not 
respected by mod_mono without a restart.  I think I have a candidate for 
a bug:

I have added this to Web.config:

<system.web>
   <webServices>
     <protocols>
       <remove name="Documentation"/>
     </protocols>
   </webServices>
   ....
   ....
   ....
<system.web>


This is not respected without a restart.  But otherwise works well.

Secondly.

For use of other members, I have found this great code snipit for 
Global.asax:

protected void Application_BeginRequest(Object sender, EventArgs e)
{
   string requestPath = Request.RawUrl.Trim().ToLower();
			
   if (!my_static_global_flag) {
     if (requestPath.IndexOf("?wsdl") > 0 ||
         requestPath.IndexOf("?disco") > 0)
       throw new HttpException(404, "Access Denied.");
   }
}

This also helps give me good control over visibility of my webservices.

-----------<>------------

Thanks for the help,

Ben
