You said you installed nqxml to get uri.rb? uri.rb got included with the 
Ruby standard library at some point, so you shouldn't need nqxml. Maybe 
that's causing a conflict, I don't know.

PROPFIND is a WebDAV method. Basically it's an HTTP POST by a different 
name. There's some voodoo at the top of dav.rb that lets the HTTP guy know 
how to process it.

Ruby is a dynamic language, so the following line:

res = http_con.method(req_method.downcase).call(path_query, req_data, 
headers)

(where req_method is 'PROPFIND') tells the Ruby compiler to call the method 
propfind(path_query, req_data, headers). It's sorta like reflection in Java, 
RTTI in C++, etc. For learning more about Ruby, I recommend the book 
Programming Ruby by Dave Thomas and Andrew Hunt. Dave Thomas is one of the 
most active members in the Ruby community and he's an all around nice guy 
(I've met him twice). The book is available online at 
http://www.rubycentral.com/book/ (the dns for the domain is messed up, so 
try http://165.193.123.250/book/ if that doesn't work).

Ok, thx for the info.  I ended up blowing away the new version I had built 
(in /usr/local/lib/ruby) and reinstalled XMLParser and nqxml just to be 
safe.  Unfortunately, I'm still getting the cookie error.  I've been looking 
over the code, and I've been able to figure out that the error is caused by 
calling extract_cookies(res) where res == nil, but beyond that, I'm lost.

Unfortunately, the cookie error is manifested using both gethttpmail.rb and 
thm.rb since they both work basically the same way.

Looking at the stack trace from the crash (reported in an earlier email), I 
see this line in the trace and it's a little confusing . . . :

		dav.rb(285): res = @session.http_wrap('PROPFIND', @uri, {}, doc.to_s)

I guess I'm a little confused at what 'PROPFIND' is, or what it does.  In 
http_wrap(), the 'PROPFIND' object has the downcase property invoked on it:

		dav.rb(134): res = http_con.method(req_method.downcase).call(path_query, 
req_data, headers)

and that call is apparently being directed to propfind() at dav.rb(55), but 
I don't understand how PROPFIND is mapped to propfind(), and where arguments 
for propfind() are located . . .

Remember, I'm a Ruby novice :) Any pointers you can give, or places you can 
recommend where I can learn more on my own would be appreciated.

Cheers,

-Dane
