How to programmatically download a file in HTML

Most HTTP clients will prompt the user to download the resource contents when they receive a response from a server like the one above. Now the server enforces a download of the GIF image. Here is what the HTTP response for the GIF image should look like to enforce file download: The disposition parameters are additional parameters that specify information about the body part or file, such as filename, creation date, modification date, read date, size, etc. Attachment: The body part is separate from the main contents of the message and should not be displayed automatically except when prompted by the user.

Inline : The body part is intended to be displayed automatically when the message content is displayed.

The disposition type is usually one of the following: This header provides information on the disposition type and disposition parameters. However, it can be interpreted by several HTTP clients, including web browsers. The Content-Disposition header was originally intended for mail user-agents , because emails are multipart documents that may contain several file attachments. The Content-Disposition header is the right header for specifying this kind of information. To inform the client that the contents of the resource are not meant to be displayed, the server must include an additional header in the response. For this, an extra header will be needed to tell the client to automatically download the contents of the file. For the purposes of this writing, what we would actually want is for the GIF or image to be downloaded instead of displayed. Given the example HTTP response from above, our web browser client would simply display or render the GIF image instead of downloading. For this example response, the Content-Type and Content-Length headers provide that kind of information. The response also contains headers that give the client some information about the nature of the contents that it receives. In this response, the server simply serves the raw contents of the resource (represented with the final two rows of asterisks - *), which will be received by the client. Here is what the response from the server could possibly look like: Though the diagram indicates the communication flow, it does not explicitly show what the request from the client looks like or what the response from the server looks like either. The orange line shows the flow of the response from the server back to the client. In this diagram, the green line shows the flow of the request from the client to the server over HTTP. The server then returns a response containing the contents of the file, as well as some instructional headers specifying how the client should download the file: Traditionally, the file to be downloaded is first requested from a server by a client , such as a user’s web browser.
