Enlist some services provided by a web server.

A web server is completely dedicated to handling requests for webpages. It provides following major services :

1. Serving Web Pages — The primary function of a webserver is to deliver web pages on the request of clients using the Hypertext Transfer Protocol (HTTP). This means delivery of HTML documents and any additional content that may be included by a document, such as images, style sheets and scripts.
2. Running Gateway Programs (CGI) and Returning Output — In order to process the requests received, the webservers need to run special programs called CGI programs which help them fetch the required output as per the request made by the client.
3. Controlling Access to the Server — A full implementation of HTTP also includes ways of receiving content from clients. This feature is used for submitting web forms, including uploading of files.
4. Monitoring and Logging all Access — The web servers also ensure that only authenticated access takes place and thus they keep running many monitoring programs and keep logging all the activities.
5. Server Side Scripting — Many generic web servers also support server-side scripting using Active Server Pages (ASP), PHP, or other scripting languages.
