I recently added the ability for our program to connect to the bing tile server and use the bing map as an overlay for our map. My work was primarily on writing the section of code that constructs the URL and uses the INDY Idhttp component to communicate with web (it basically acts as a browser so we can display the tiles on a form rather than a webpage). Recently several clients have stated that they are unable to to access the tile server. We quickly realized it was environment specific. Two clients resolved this by adding exceptions to there Firewall settings. The remaining client uses a Proxy server, which we never planned for. Is anyone familiar with setting up the Idhttp component to use a proxy server? What are the parameters and or settings that must be used? Any help pointing me in the right direction would be greatly appreciated. I am fairly new to the concept of Proxy servers. Thanks in advance.
