GOAL:
What effect will proxy server have on webspeed configurations?
GOAL:
Will adding a proxy server in front of web server affect any webspeed configurations?
GOAL:
What is proxy server?
FACT(s) (Environment):
Progress 9.x
OpenEdge 10.x
WebSpeed 3.x
FIX:
Proxy server is defined as "A server that sits between a client application, such as a web browser, and a real server. It intercepts all requests to the real server to see if it can fulfill the requests itself. If not, it forwards the request to the real server."
With following configuration
browser <--> proxy <----> Web server (messenger) <-----> WebSpeed (transaction server)
There is no need to change webspeed configuration. The requests from the browser will either be served by proxy directly (if the proxy has the page in its cache) or passed to web server (webspeed messenger).
If you configure the proxy to do load-balancing or URL redirection to more than one web servers, you will need to install messenger on each of the web server and configure the messengers to connect to the broker. Again here the proxy server is being used a load balancer in front of IIS, it balances and redirects requests from the browser to the appropriate web server prior to requests reaching the web server (messenger).
