What is an ASP file?

Asp file extension has Active Server Page file type, developed by Microsoft, which is associated with the "web files" category.

Server page file contains HTML, which is then sent to the user browser. Such files are typically associated with ASP.NET websites that are hosted on Windows servers, which run Microsoft IIS.

Unlike .HTML files, when .ASP files are requested by a browser, the server proceeds with the request via the ASP engine. The latter parses .ASP files, generating HTML that is sent to the user web browser. Since .ASP pages are processed on the server, .ASP code is usually not visible to website visitors. .ASP pages commonly come with the “.ASP” file extension, instead of the “.HTML” extension.
