Troubleshoot tricky web customer issues with web server logs

Troubleshooting client problems related to your website may be tricky if you don't know which servers processed a given client's web request. This task may seem more difficult when using load balancers, CAS servers, and other equipment that distributes requests across various servers. To find out which servers processed a given client's request and what happened, look at the web server logs. There are many tools available to make sense of the logged data. For example, if your web server is IIS, you could use a tool such as IIS Log Analyzer.
