I’m writing a servlet subclassed from  
WEBrick::HTTPServlet::AbstractServlet  
to be used in a WEBrick::HTTPServer over ssl.

When the servlet receives the instance of WEBrick::HTTPRequest passed  
into it’s constructor, that instance contains an attribute called  
@client\_cert.

The server is configured to require and verify a client web browser  
certificate,  
and everthing works as expected. But @client\_cert seems to be always set  
to nil.  
I need to somehow obtain the .pem encoded client cert, and extract some  
of  
it’s  
elements.

Perhaps I have overlooked something in the instantiation of my servlet,  
or the https server itself. Complete documentation of this API seems  
scarce.  
Any advice or pointers to documentation would be appreciated.
