Html Download A File From Server

At the most basic level, whenever a browser needs a file that is hosted on a web server, the browser requests the file via HTTP. When the request reaches the correct (hardware) web server, the (software) HTTP server accepts the request, finds the requested document, and sends it back to the browser, also through HTTP. (If the server doesn't find the requested document, it returns a 404 response instead.)

A dynamic web server consists of a static web server plus extra software, most commonly an application server and a database. We call it "dynamic" because the application server updates the hosted files before sending content to your browser via the HTTP server.

For example, to produce the final webpages you see in the browser, the application server might fill an HTML template with content from a database. Sites like MDN or Wikipedia have thousands of webpages. Typically, these kinds of sites are composed of only a few HTML templates and a giant database, rather than thousands of static HTML documents. This setup makes it easier to maintain and deliver the content.

To review: to fetch a webpage, your browser sends a request to the web server, which searches for the requested file in its own storage space. Upon finding the file, the server reads it, processes it as needed, and sends it to the browser. Let's look at those steps in more detail.

For all these reasons, finding a good hosting provider is a key part of building your website. Examine the various services companies offer. Choose one that fits your needs and budget. (Services range from free to thousands of dollars per month.) You can find more details in this article.

Second, a web server provides support for HTTP (Hypertext Transfer Protocol). As its name implies, HTTP specifies how to transfer hypertext (linked web documents) between two computers.

Neither the server nor the client remember previous communications. For example, relying on HTTP alone, a server can't remember a password you typed or remember your progress on an incomplete transaction. You need an application server for tasks like that. (We'll cover that sort of technology in other articles.)

Roughly speaking, a server can serve either static or dynamic content. Remember that the term static means "served as-is". Static websites are the easiest to set up, so we suggest you make your first site a static site.

The term dynamic means that the server processes the content or even generates it on the fly from a database. This approach provides more flexibility, but the technical stack is more complex, making it dramatically more challenging to build a website.

It is impossible to suggest a single off-the-shelf application server that will be the right solution for every possible use case. Some application servers are designed to host and manage blogs, wikis, or e-commerce solutions, while others are more generic. If you're building a dynamic website, take the time to research your requirements and find the technology that best fits your needs.

Most website developers won't need to create an application server from scratch, because there are so many off-the-shelf solutions, many of which are highly configurable. But if you do need to create your own server, then you will probably want to use a server framework, leveraging its existing code and libraries, and extending just the parts that you need in order to meet your use case. Only a relatively small number of developers should need to develop a server completely from scratch: for example, in order to meet tight resource constraints on an embedded system. If you'd like to experiment with building a server, take a look through the resources in the Server-side website programming learning pathway.

A static web server, or stack, consists of a computer (hardware) with an HTTP server (software). We call it \"static\" because the server sends its hosted files as-is to your browser.

A dynamic web server consists of a static web server plus extra software, most commonly an application server and a database. We call it \"dynamic\" because the application server updates the hosted files before sending content to your browser via the HTTP server.

Welcome to the MDN beginner's server-side programming course! In this first article, we look at server-side programming from a high level, answering questions such as "what is it?", "how does it differ from client-side programming?", and "why it is so useful?". After reading this article you'll understand the additional power available to websites through server-side coding.

Most large-scale websites use server-side code to dynamically display different data when needed, generally pulled out of a database stored on a server and sent to the client to be displayed via some code (e.g. HTML and JavaScript).

Web browsers communicate with web servers using the HyperText Transfer Protocol (HTTP). When you click a link on a web page, submit a form, or run a search, an HTTP request is sent from your browser to the target server.

Web servers wait for client request messages, process them when they arrive, and reply to the web browser with an HTTP response message. The response contains a status line indicating whether or not the request succeeded (e.g. "HTTP/1.1 200 OK" for success).

The diagram below shows a basic web server architecture for a static site (a static site is one that returns the same hard-coded content from the server whenever a particular resource is requested). When a user wants to navigate to a page, the browser sends an HTTP "GET" request specifying its URL.

The server retrieves the requested document from its file system and returns an HTTP response containing the document and a success status (usually 200 OK). If the file cannot be retrieved for some reason, an error status is returned (see client error responses and server error responses).

A dynamic website is one where some of the response content is generated dynamically, only when needed. On a dynamic website HTML pages are normally created by inserting data from a database into placeholders in HTML templates (this is a much more efficient way of storing large amounts of content than using static websites).

The diagram below shows a simple architecture for a dynamic website. As in the previous diagram, browsers send HTTP requests to the server, then the server processes the requests and returns appropriate HTTP responses. e24fc04721
