  How to set up proxy?

  Aug 12, 2003 04:17 PM|LINK

  Probably a simple question. How do you set up Rainbow to communicate through a proxy server? I have attempted to edit web.config with the following details: the details are all correct for the ISA server we are using and are the same settings as all the client browsers. i know i cannot see the net as dilbert and news feeds do not work. Any assistance would be appreciated.

  The fact is that the ProxyServer field is present in web.config, but none of the Desktop modules uses it! (It should be accessed via PortalSettings.GetProxy()) I made the changes in the DailyDilbert and XmlFeed modules. Just replace the Rainbow\DesktopModules\DailyDilbert\DailyDilbertImage.aspx.cs and Rainbow\DesktopModules\DailyDilbert\DailyDilbertImage.aspx.cs files with the following ones and rebuild the application. Hi folks of the development team! Could you incorporate my changes? Rainbow\DesktopModules\DailyDilbert\DailyDilbertImage.aspx.cs ==========================================
