APD-Soft develops applications and active server components for Windows-based MS IIS web servers, utilizing primarily ISAPI server extension technology.

We also develop Windows-based client applications and components to provide customized client-server interaction and data exchange with the web servers and other Internet servers.

What is a benefit of MS IIS web server platform?

Windows-based web server is a logical Internet solution for small and medium size businesses, easy to deploy, to maintain, control, and to integrate with existing local network infrastructure. It has become more and more popular while more companies need to establish and to advance their Internet presence.

We believe that MS IIS platform has been erroneously perceived by web developers as too complex and less reliable compared to Linux and other competitors. Most of its complexity, vulnerability, compatibility issues are actually associated with the later Microsoft add-on technologies including .NET, ASP/ASPX, various DCOM-based implementations and other proprietary (and indeed highly unreliable and poorly backwards compatible) new technologies vigorously pushed by Microsoft in a desperate attempt to change the nature of software development evolution into a direction which would be benefitial for preserving its monopoly.

However, if configured properly, with most of non-native Microsoft add-ons stripped, MS IIS web server can be very robust, reliable, secure, and more effective than other web platforms.

What is a benefit of using ISAPI?

Microsoft ISAPI technology is the most robust and effective approach for developing web server applications running on MS IIS platform. It is the only native web application technology for MS IIS. It takes the best from IIS and Windows NT architecture and, when used properly, allows to achieve highest performance and the most extensive functionality on a very regular web server running on a regular Windows machine.

This native technology was not originally well documented by Microsoft who kind of tried to keep it for themselves. Perhaps this is the reason why ISAPI technology is not used as widely as it deserves. However, it is internally a base for all ASP and other upper level web component implementations developed by Microsoft on IIS platform.

One of the main advantages of ISAPI server extension technology is deeper integration of the application with the server. Unlike with CGI scripts or ASP active components, server does not need to load, to launch, and then to unload a new application task every time when an active request from user has to be served. ISAPI technology directly integrates web server functionality with the native Windows system environment. Since ISAPI application can take full advantage of all general Windows APIs, it makes a much wider scope of functionality available to a developer.

We offer publicly some of our web-server as well as end-user level products and applications which can be of interest to web server administrators and Internet users, can be easily installed and do not require special deployment support on the part of APD-Soft.

A-Forum Software for web-based
discussions and message boards

This is a good example of web server ISAPI application which is easy to install and which immediately turns a static web server into an active engine automatically managing text content published by users. It offers various customizing capabilities and some extended functionality, like automated email notifications and instant private email responses to posted messages.

Apdsoft Web Mailer for MS IIS

This is an ISAPI server application which allows users to send you customized mail requests directly from your web site by filling out a form and clicking on the button. You will no longer need to publish your email address on the server - it will be defined in internal settings and thus will be hidden from spam robots.

Apdsoft Web Mailer can work with or without SMTP server being available. It has its own embedded SMTP service complying with RFC821 standard. This is an example of special functionality implemented inside ISAPI server extension.

Apdsoft Mail Filter and Forwarder for Windows

This is end-user level application for Windows which is designed to filter spam and to manage incoming mail for those who has extensive email correspondence, several POP3 mailboxes, different mail aliases etc. It allows to filter mail, automatically reject and delete it depending on content and other properties, to send automated replies, to forward mail from one mailbox to another, etc.

It can be helpful for small and medium size companies to manage, filter and forward incoming POP3 mail - if used in automated unattended mode on a regular Windows computer permanently connected to Internet. It can also be used to detect and read new incoming mail from the mail server without opening any other mail program.

Mail Filtering Software for MS IIS

This is MS IIS server software which works on your web server 24 hours a day in a tandem with any existing POP3 server and filters mail which is received and stored by that server. It is controlled by the administrator remotely using a web-based Interface and can be deployed on a remotely hosted web site. The POP3 server can actually be located on a different local network anywhere in the Internet.

Helpful for small and medium size businesses to manage, filter and forward incoming mail.

Forum Hosting Service

We also provide remote hosting for web forums and message boards for individuals and small businesses. This may be helpful for those who does not have own MS IIS web server but wants to use our A-Forum software.
