Go Web Server

This project includes a simple Go web server that serves static files.

How to Run

1. Make sure you have Go installed (https://golang.org/dl/).

2. By default, the server will look for a config.json file in the project root. Example config.json:

   {
     "homedir": "./html",
     "port": "80",
     "error_pages": {
       "404": "./html/404.html",
       "500": "./html/500.html"
     }
   }

   • homedir: Directory to serve static files from (default: ./public)
   • port: Port to serve HTTP on (default: 80)
   • error_pages: Paths to custom error pages for 404 and 500 errors (optional)

3. To run the server:

   go run main.go

   • You can specify a different config file with the -config flag:

     go run main.go -config=/path/to/your/config.json

   • You can override config file values with flags:

     go run main.go -homedir=/tmp/files -port=8080

     Flags take precedence over config file values.

4. Place your static files (e.g., index.html, picture.jpg, file.js) in the home directory.

5. Open your browser and go to http://localhost:<port> to see the server response.

Custom Error Pages

• You can specify custom error pages for 404 (Not Found) and 500 (Internal Server Error) in config.json under the error_pages field.
• If a requested file is not found, the server will serve the specified 404 page. If the 404 page is missing, a default message is shown.
• If a server error occurs, the server will serve the specified 500 page (future support for 500 errors).
• Example error pages are provided in the public folder.

Default Home Directory

• The default directory for static files is ./html.
• An example index.html is provided in the html folder.
• You can add more files (images, JavaScript, etc.) to this directory to have them served by the web server.
