Frameworks like Node.js, Django, Flask, Spring Boot, and various API services often listen on these ports instead of directly serving traffic through ports <strong data-start=\"493\" data-end=\"499\">80<\/strong> (HTTP) or <strong data-start=\"510\" data-end=\"517\">443<\/strong> (HTTPS).<\/p>\n<p data-start=\"528\" data-end=\"789\">While exposing these application ports directly to the internet may work, it is generally not considered a best practice. Doing so can create management challenges, complicate SSL\/TLS implementation, and expose internal application infrastructure unnecessarily.<\/p>\n<p data-start=\"791\" data-end=\"1153\">A better approach is to place <strong data-start=\"821\" data-end=\"843\">Apache HTTP Server<\/strong> in front of the application and configure it as a <strong data-start=\"894\" data-end=\"911\">reverse proxy<\/strong>. Apache receives incoming requests on standard web ports and transparently forwards them to the backend application. Users continue to access the website using the main domain name, while the backend application remains hidden behind Apache.<\/p>\n<p data-start=\"1155\" data-end=\"1192\">This setup offers several advantages:<\/p>\n\n<ul data-start=\"1194\" data-end=\"1580\">\n \t<li data-section-id=\"fu4etp\" data-start=\"1194\" data-end=\"1253\">Keeps backend application ports hidden from public
