           Summary: Dreamweaver 8 Webdav times out and fails
           Product: Tomcat 5
           Version: 5.5.9
          Platform: All
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: [EMAIL PROTECTED]


I've been implementing a webapp with webDAV functionality for a client, and 
have been hitting webDAV timeout problems when using Dreamweaver 8 as the 
client. I've searched google and bugzilla, and most of the articles are circa 
Tomcat 4, so I suspect there is something in the way the latest version of 
Dreamweaver is communicating that Tomcat doesn't know how to handle.

A quick summary of my testing:

- With my custom webapp, my own container (Winstone) works fine, Resin works 
fine and Tomcat locks up. 
- Even with tomcat's bundled webDAV application, Dreamweaver gets some 
intermittent errors to do with HTTP timeouts. Creating new folders brings up a 
dialog saying something like (rough translation from Japanese) "Can't GET 
remote folder information", but does it anyway.
- This timeout problem occurs on 5.0.30 and 5.5.17.
- The server believes that the response has been finished, but client hangs 
waiting. It seems to be just after a PROPFIND that is asking for lockdiscovery 
and resourcetype.
- Other clients are fine (MS WebFolders, MS Office, Gnome DAV client)
- My custom app is DAV level 2.

>From looking at the headers passed back and forth, the main difference appears 
to be use of the Connection:close header (resin and winstone both use it in 
places that Tomcat doesn't). That leads me to believe that dreamweaver is 
confused when trying to keep-alive a tomcat connection that is closed by 
winstone and resin.

I'm happy to continue trying to debug this, because I expect there's probably 
some webapp workaround that won't require any container changes, but I'd like 
to ask 2 questions:

1. Is there a tomcat debug setting that dumps headers and responses to the 
logs (so I can watch keep-alive behaviour while it's failing) ? I've looked 
and I couldn't see one.
2. Has anyone else had successful use of Dreamweaver 8 with Tomcat using 
webdav ?

Thanks, 

Rick
