Lighttpd

Case A:
I configured my lighttpd.conf file(in my source 'a.b.c.d' system) to proxy to server(p.q.r.s) on port 80. When i type ip address 'a.b.c.d' in url then i can see the proxy opening (of p.q.r.s)..means i am able to see the contents of p.q.r.s on a.b.c.d.

a.b.c.d and p.q.r.s are valid ip address. I have attached the lighttpd.conf file with which this part is working.

Case B:
I configured my lighttpd.conf file(in my source 'a.b.c.d' system) to proxy to server(p.q.r.s) on port 443. When i type ip address 'a.b.c.d' in url then i cannot see any thing opening means the page is blank.

only the change made in the attached lighttpd.conf for this part is changing the port no to 443, as below:

proxy.server = ( "" =>
("localhost" =>
(
"host" => "p.q.r.s",
"port" => 443
)
)
)

I could see from my firebug debugger that the request is going from a.b.c.d to p.q.r.s but there is no response coming back.

When i saw the log on p.q.r.s then it is showing like this..

2000-01-02 04:19:42: (log.c.166) server started

Note: The same server is working on port 80 but not for port 443.
version of lighttpd:
lighttpd/1.4.28 (ssl) - a light and fast webserver
Build-Date: Mar 22 2012 19:38:03

Is there any settings missed that needs to be done for supporting https(:443)?
