It would be helpful to see the content that is being passed around between client, web server and upstream (downstream) content server.<br />
<br />
1. What is the content format being served from the content server?<br />
2. What is the relationship between the client (browser), the IIS Server and the content server?<br />

Hi,<br />
I am working on a browser based application. If the transaction is a bit longer I got response<br />
<br />
502 - Web server received an invalid response while acting as a gateway or proxy server.<br />
There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.<br />
<br />
How to avoid this? Any configuration changes on IIS can resolve the issue?

IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.

Microsoft IIS Web Server

Web applications are systems that run in browsers that perform functions normally associated with other client-based programs. One of the most commonly used web applications is email; instead of downloading individual emails to a local machine, the data is shown through a website. Other examples of web applications are collaborative systems like a wiki or an online game.
