Here's an HTTP Server written in COBOL.
For compilation, you'll need GnuCOBOL 3.1.2.0. Please consider that it had been tested only on a Linux system and is currently only using Linux system calls.
git clone https://github.com/HashDG/http-server-cobol.git
cd http-server-cobol
make
./http-server <host> <port>
In order to ensure the proper running of the server, just visit the link http://host:port/
in your browser.
The server answer Hello World (yahoo). This version is testing (unsuccessfully) HTML files scraping. If you want to execute it well, just remove the call to HTTP-RESOURCES-SCRAPER.
