HTTP/2 REST client and service for secure image file upload to IIS server

What: • Windows Server REST service and Windows client REST client to safely and quickly upload one very high resolution photo (can be more than 100MB) on an IIS server How: • C# command line tool on Win10 PC to push one photo o Client tool sends a REST request to server service with two information: - PC user domain and login name (from current session) - A static string “ABCD” • REST service on Windows 2012 server with IIS o REST service receiving requests from clients - PC user domain and login name (from current session) • Just for information, not used - A static string “ABCD” • If the string does not match “ABCD” (hardcoded) then the request is declined • If there are more than 10 wrong strings in a row from the same IP address, then the REST service returns “DECLINED” for 10 minutes o The REST service then builds and returns a complex URL (minimum 40 random upper/lower chars and digits after the main URL) where the client tool performs a HTTP/2 POST of one binary file, using HTTPS (mandatory on IIS) • A URL can only be open once • A URL shall accept only one file upload and become void afterward • If a URL is not used within 1 minute, it shall be unusable • File uploads happen in one folder (hardcoded) o The REST service shall confirm to the client the file has been received correctly or any error. Technology: • HTTP/2 protocol (mandatory to make binary POST transfers) • C# client and server • Multi-threading Bandwidth support requirements: • A minimum of 10K simultaneous REST requests shall be supported through multi-threading • The standard IIS POST system shall be used, with HTTPS /2 • Source code shall be commented, one comment per line, describing the role of that line
