After setting up the ARR server Farm and url rewrite rule which is created by default. I end up with 502.2 error Error Summary HTTP Error 502.4 - Bad Gateway No appropriate server could be found to route the request. Detailed Error Information Module ApplicationRequestRouting
Notification MapRequestHandler Handler ApplicationRequestRoutingHandler Error Code 0x00000000 Requested URL http://siteb:80/ Physical Path d:\Test\2 Logon Method Anonymous Logon User Anonymous Most likely causes: The CGI application did not return a valid
set of HTTP errors. A server acting as a proxy or gateway was unable to process the request due to an error in a parent gateway. Things you can try: Use DebugDiag to troubleshoot the CGI application. Determine if a proxy or gateway is responsible for this
error. Links and More Information This error occurs when a CGI application does not return a valid set of HTTP headers, or when a proxy or gateway was unable to send the request to a parent gateway. You may need to get a network trace or contact the proxy
server administrator, if it is not a CGI problem. I have been trying to setup the ARR and am struck now, pardon me if i missed something i am a newbie to IIS7 and ARR. lemme knwo in case some more information is required to trbleshoot this issue. Thanks Harneet
What is your url rewriter rule and server farm look like?
Please make sure that all the application servers/sites are accessible from your ARR server. Also make sure that your server farm is not disabled. And none of the servers in server farm are disabled or unhealthy.

You may want to enable failed request tracing for both URL rewrite and ARR and provide more detailed tracing info for troubleshooting.
If you are not familiar with failred request tracing, refer to the following doc at http://learn.iis.net/page.aspx/488/using-failed-request-tracing-rules-to-troubleshoot-application-request-routing-arr/
