HttpClientTesting

Console app to measure the time taken to upload file to S3 and Azure blob storage. Total 5 requests are sent one after the other to the specified endpoint. The utility will log well known http, socket and name resolution events (https://learn.microsoft.com/en-us/dotnet/core/diagnostics/well-known-event-providers) in the console to understand which step is actually taking time.

Steps to run the console application -

1. Compile the project in release mode. Use the dotnet 6 command line -

   dotnet build HttpClientTesting.sln --configuration release

2. Open the appsettings.json file from the .net6 release folder of HttpClientTesting project. Below is the description of each option in appsettings.

   I. filePath - path of the file that needs to be uploaded.

   II. waitAfterEachRequest - specify whether the client wait after each upload request. If true, then the next upload request will be sent after waiting for 10 seconds.

   III. usenet6 - specify which version of HttpClient to be used. If true, uses .net 6 HttpClient else use .net standard 2.0 HttpClient.

   IV. testClient - specify whether to use Azure or AWS to upload file. Default blank is to use AWS and if set to "azure", then Azure blob storage is used.

   V. aws - has AWS specific configuration.

   A. baseURL - is the S3 domain with protocol like "https://test.amazonaws.com/"
   
   B. relativeUploadURL - is the S3 bucket URL
   
   C. sendDummyRequest (optional) - specify whether to send a dummy request to the S3 domain before sending the actual file upload request. If true, sends a GET request before the file upload request.
   

   VI. azure - has Azure specific configuration.

   A. connectionString - Azure blob storage connection string
   
   B. containerName - Azure blob container name in which file will be uploaded.
   
   C. closeConnection (optional) - whether to close connection between client and Azure after each request. If true, closes connection else connection remains open till Azure closes the connection.
