title: Web API call sent 3 times in Azure App Service
body: <p>We are using Azure Web App Service to host our backend API in .NET 4.6.</p>
  <p>We saw a particular web API ran 3 times exactly after 2 minutes interval. Out of those 3 runs, one should be triggered from the front end app (Angular 7 app hosted on Azure App Service). So the web API ran extra 2 times.</p>
  <p>Observations:</p>
  <ol>
  <li><p>This particular API ran for 8-10 minutes due to large number of files processing in each run. This was an exception generally it completes within a minute. All the required processing was done without any issue in three runs of API.</p>
  </li>
  <li><p>I verified the front end code and it won't call the API more than one. So I am not able to figure out why the API ran extra for 2 times? Is it due to any time out related setting in .NET or in Azure Web App?</p>
  </li>
  <li><p>This has not happened so far and is particularly observed for one specific person. May it be browser related issue?</p>
  </li>
  </ol>
  <p>Any pointer on how to segregate issue whether it is related to .NET/Azure application or something else would be helpful.</p>
  <p>Thank you!</p>
