Proxy to External App Broken?

Under one Virtual host, I have created an 'External App', like so:

Name: yap
Address: 192.168.1.200:80

Then under 'Rewrite', I have:

Enable Rewrite: yes
Log Level: 9

Rewrite Rules:
RewriteRule ^/(.*)$ http://yap/$1 [P]

-----------------------------------------

But when I try to request anything from this virtual host, the request hangs indefinitely!

error.log says:
015-11-23 16:06:42.804 [INFO] [192.168.1.52:58821] [REWRITE] Rule: Match '/hello.png' with pattern '^/(.*)$', result: 2
2015-11-23 16:06:42.804 [INFO] [192.168.1.52:58821] [REWRITE] Source URI: '/hello.png' => Result URI: 'http://yap/hello.png'
2015-11-23 16:06:42.804 [INFO] [192.168.1.52:58821] [REWRITE] Last Rule, stop!

I use wget to test, and the request looks like this:

$ wget -S "http://litespeed-test.com/hello.png"
--2015-11-23 16:06:42-- http://litespeed-test.com/hello.png
Resolving litespeed-test.com (litespeed-test.com)... 192.168.1.205
Connecting to litespeed-test.com (litespeed-test.com)|192.168.1.205|:80... connected.
HTTP request sent, awaiting response...

And that's it. Will stay like that indefinitely. Needless to say there is another webserver listening on 192.168.1.200:80, and there are no firewalls involved.

Why would Litespeed do this?

Certainly, here is that wget cmd:

$ wget -S http://192.168.1.200/hello.png
--2015-11-23 20:11:50-- http://192.168.1.200/hello.png
Connecting to 192.168.1.200:80... connected.

Thanks for looking at my problem!

EDIT:

The above is on another server on the private network. The below is on 192.168.1.205 specifically, as you can see in the following wget cmd:

$ wget --bind-address 192.168.1.205 -S http://192.168.1.200/hello.png
--2015-11-23 20:14:44-- http://192.168.1.200/hello.png

Here is 'yap':



And if I turn rewrite off:

$ curl -I "http://litespeed-test.com/"
HTTP/1.1 200 OK
Etag: "752-56536150-622660"
Last-Modified: Mon, 23 Nov 2015 18:56:16 GMT

Content-Length: 1874
Accept-Ranges: bytes
Date: Tue, 24 Nov 2015 04:36:29 GMT
Server: LiteSpeed

EDIT:

ps: litespeed-test.com is pointed to 192.168.1.205 in my hosts)
$ ping litespeed-test.com
PING litespeed-test.com (192.168.1.205)

Ok, set the yap config exactly as you suggest above, and I set server Log Level: Debug and Debug Level: High.

This is what the log says now, as I make the request:
