KF Web Server is a free HTTP Server that is able to host an unlimited number of web sites.

Its small size, low system requirements and easy administration make it the perfect choice for both professional and amateur web developers alike.

It supports CGI, advanced security settings including MaxURLSize and more, multiple ports, file caching, MIME settings, directory indexes and also browser based, remote administration. The configuration interface is easy to use and attractive.

Here are some key features of "KF Web Server":

KF Web Server Features
· Free - No licence fees, time limits or SpyWare included.
· Unlimited web sites - Can host an unlimited number of web sites, each with their own home directories and security configurations.
· Multiple domain names, multiple ports - Map different domain names on to one or more web sites. Listen on many ports at the same time. No need to limit yourself to the standard port 80.

Core Functionality
· HTTP/1.1 support - Implements the latest HTTP standard, 1.1 to provide request pipelining, range downloads and browser cache support for enhanced performance.
· CGI/1.1 - Works great with PHP, PERL, Python and other scripting languages.
For security reasons the running of arbitrary executables is restricted.
· HTTP Compression - Implements standard HTTP gzip compression to increase your performance by up to three times.
· Directory indexes - Supports standard file name substitution, such as index.html, if a client only asks for a directory.
Directory listings can also be generated automatically using a configurable script to suit your needs.
· File cache - Files are cached in memory for faster performance.
· MIME settings - Use the pre-defined MIME file associations, or define your own.
· Custom error messages - Define your own server error message format.
· Logging - Supports the two industry standard log file formats, NCSA and W3C. Each web site can have its own request log file and request times can be written in local time or in Greenwich Mean Time. The log files are compatible with the many web server log analysis applications available.
· Permalinks - Supports addition path info for CGI scripts and a powerful URL re-write rules feature.
· Advanced engine - KFWS was written from the ground up in C++ as a multithreaded Windows application.
Supports Windows 98,ME,2000 and XP.
It is self contained and requires no external libraries on run-time DLLs, other than those shipped as part of the Windows operating system.
· System Service - Can be installed as a systems service on Windows NT,2000 and XP, for enhanced security and administration.
It can be run as a conventional application on Windows 98 and ME.

Administration
· Browser based administration
Configure the server through your browser from any machine on the internet. For security reasons this is initially restricted to the local machine, but a simple setting change enables remote administration.
· System Tray monitor
The server sits as an icon in your system tray and can be configured to start manually or when you boot up.
· Highly configurable
Gives you detailed control over all aspect of the servers operations.

Security
· Multiple security realms
HTTP standard Basic Authentication is based on user names and passwords defined within a realm. KFWS supports an unlimited number of realms, each with their own set of users and user groups.
· Directory security
Set security permissions at the individual sub-directory level. Gives you maximum flexibility on implementing your security policies.
· Hacker protection
Not everyone browsing is friendly and KFWS has many built-in security features to protect against attacks:
· Password failure timed lock outs, to prevent dictionary attacks.
· Request limits to counter Denial Of Service attacks.
· Fail safe operation. Only those requests that pass all the security checks, such as a recognised MIME type and an authorised directory will be authorised. Prevents hackers from accessing system files or executing unauthorised applications.

What's New in This Release: [ read full changelog ]

· User Interface Improvements - A link to the hosted website has been added to each website in the status menu, allowing the web site to be viewed by a single click.
· Additional Path Info - We have added support for additional virtual directories in the URL as described in the CGI standard. Many scripts use this facility to pass parameters to the script without the need for a query. This has the benefit of providing permalinks.
· URL Re-write Rules - URL Rewrite Rules are a powerful feature that allows you to manipulate the URL received by the web server into a different form.
