In which cases is it relevant to maintain and develop your Classic ASP?

Many systems and sites have been developed in Classic ASP. This language being very widespread, it was used in the same way as the PHP today: sometimes in a correct way, sometimes in a more lax way. The consequence is that many mistakes were made by the first Classic ASP developers. Poor final product quality and messy user experience has unfortunately been very common, leading to bottlenecks, delays, session or security issues, as well as expensive database accesses. Classic ASP is often described as a "bad language", just like PHP... wrongly. After all, every language is only a tool, and it is quite possible to develop poorly, even in C ++.

Our experience with ASP 3 makes us the specialists you need to solve these malfunctions, as they are absolutely not a fatality. We pinpoint the problems that affect your ASP code execution. Well developed, Classic ASP site / application has absolutely no blush, and offers really excellent performance. Let us help you rediscover the potential of your existing codebase through our work of optimization, redesign, streamlining, troubleshooting or rewriting.

Add the missing piece to your Classic ASP infrastructure

Consider maintaining your Classic ASP in the following cases

Our Classic ASP maintenance and support service is ideal if you need to achieve one of the following:


Fine-tune your Windows and IIS server configuration

Our area of expertise is not limited to your source code. Thus, we are also competent to improve the server infrastructure in charge of executing your scripts, including:

Our full-stack approach keeps you away from the following bad practices

We understand the business implications of each project before coding anything. This unique skills mix makes us able to provide a very end-to-end approach.

It is quite common that too much Classic ASP developers have coded "On-the-go". This can result in unstructured and messy scripts that are hard to evolve, and sometimes almost unmanageable. This introduces useless complexity in code structure, while ignoring the use of beneficial OOP (Object-Oriented-Programming) concepts. But the ASP platform is not flawed by design. We use it in an efficient manner on a daily basis, and are able to produce 100% clean code.

Here are some of the most common glitches your existing code may suffer from. If you are in one of the following cases, your code can benefit from our rewriting service:

What is it possible to achieve with Classic ASP?

Classic ASP Source code snippet

We are regularly astonished at the sneers our customers get when the mention their Classic ASP system. C, COBOL or assemby are old, and still widely used. In fact, just because Classic ASP is old does not mean it is worn out… nothing could be further from the truth ! Our experience allows us to perform the maintenance of your ASP system, as the recovery and migration of your application, in the best conditions. We assure you to be able to evolve very quickly, while preserving and valuing your past investments and existing assets.

Classic ASP has standed the test of time. Why ? Simply because it's a powerful platform still delivering the expected results. For more than 22 years, our expertise in Classic ASP development led us to maintain more than 420 large or medium ASP sites, intranets and enterprise systems, hosted on different servers; we are qualified to integrate 2024 web technologies into your Classic ASP website, for example:

Moreover, you should stop thinking that Classic ASP is unable to deliver modern UI/UX. On the contrary, it is more than capable of it! Being more than pure academic and algorithmic programmers, we are perfectly skilled to produce nice user experiences using the cutting edge latest technologies (Ajax, JSON, SVG, CSS4, Responsiveness, …).

Handle accented characters predictably

Dealing with international characters and diacritics in Classic ASP can be painful. But not for us. We have built a solid knowledge in this field. Consequently, we are accustomed to deal with multiple charsets, and the UTF-8 charset is our preferred one as it allows your Classic ASP app to handle international characters with confidence and reliability.

Take advantage of our skills to put in place a strong (re)foundation in your source code, and finally make all the components sing in unison. The improvements we make on your source code will ensure that every international character is properly received, encoded, stored, and displayed, both in your webpages (ASP, HTML, Javascript) and in your database systems.

If you are using MySQL or MariaDB databases, you know that the UTF8_UNICODE_CI encoding is actually not fully compliant with the UTF8 standard. We have the required knowledge to correctly convert your database to the UTF8_MB4 format, allowing you to reliably store a larger number of characters, like emojis ☺️ !
