Write a web server for .net

 There is a project https://github.com/leon-mbs/pservernet

 A server that is accessed via JavaScript from the browser (from the accounting system page)

 if you need to print a receipt or print a label on a product, and printing directly from the browser 

 using the system printer is not suitable in terms of quality

 The problem arises if the print server (running where the printer is connected) is accessed from

 a browser open on another computer (or tablet via wi-fi) in the network.

 If the site from which the print server is accessed is hosted

 the CORS issue is compounded by the problem of mixing http and https

 Need to.

 Check that the server works with CORS requests (JavaScript via AJAX and not  the address  bar  or  Postman) from another host in the network]

 If there are problems – fix them. 

 Complete it so that the server can operate in https mode.

 Support for both http (main) and https is needed with reconfiguration in the config.

 Generate an example of an SSL certificate (for IP 127.0.0.1) indicating where to insert it.

 Write instructions for creating a self-signed certificate in Windows or a link to the instructions

 Users of the program are usually NOT IT specialists, they cannot rebuild the program from the sources  so it is necessary that

 it can be switched to https in appsettings.json (or create a separate config like appsettings_ssl.json and let them rename the file)

 With the printer  nothing needs to be  done - there  is a command /check to check the response of the print server
