FAQ – Frequently Asked Questions

ASP.NET hosting is a technology and coding language used on servers to create websites. It is used every time you select Windows hosting. ASP.NET hosting is a common, stable and extensive solution, which is why IONOS offers it alongside Linux within our hosting packages. It is based on the .NET framework, which makes it very effective when working with other Windows applications. With the web platform, Microsoft offers all the functions that are needed to bring server-based content and applications online with high performance. One of the biggest advantages of ASP.NET hosting is that it is compatible with all of the most important web standards. ASP hosting goes hand in hand with coding languages such as PHP, Java and C#, which guarantees full compatibility of your hosting package with your project. The mix of flexibility and harmonisation makes ASP.NET hosting an effective technology for reducing development time and raising the performance of your project.

With Windows hosting, we provide you with all the opportunities you need to present modern dynamic web content. A website is dynamic when it can do more than displaying simple HTML content, so visitors can influence the site in an interactive way. Also, user entries are stored in a database and other services are easy to add. Windows hosting makes it possible to use the whole bandwidth of applications of the .NET framework. Using ASP web hosting provides the benefit of tools such as ASP.NET, AJAX and MVC. For those who are not used to coding languages, IONOS includes NetObjects Fusion in all hosting packages. This tool completes obligatory code blocks and shows you syntax errors in your code. With our website builder, you can create fully functional websites without any programming skills. In just four steps you are able to choose layout and page settings for a website that fits your requirements.

For providing optimal performance of your online content, windows server hosting uses the most up-to-date technology. A key element is the Content Delivery Network (CDN), which spreads requests across several data centres so an additional performance boost is possible for your Windows server hosting platform. Users request your website from the nearest server via the cloud, which are distributed on more than 20 data centres worldwide. Websites with a lot of content such as images benefit from the mirage function of Windows server hosting. It notices the viewport and bit rate of a user, and the resolution of images is set for the best balance between quality and speed. Our WebSpace explorer is also an effective interface for loading data to your server. You can easily start it with your web browser, so an FTP client is not necessary. Another easy way to provide data for your ASP server is with WebDAV. You can configure this tool as a network drive and coordinate your data in a folder structure. You can configure your basic settings such as contact details in the control panel.

At IONOS you can use ASP hosting in different Windows hosting packages. All options include full functionality and extensive compatibility of ASP hosting. Choose the matching package for your personal volume and performance speed requirements. You can also use different software packages with our ASP hosting. With IONOS content modules you can build code sequences for content blocks that are ready to use for your website. And don't forget to choose a popular domain extension such as .com, .net or .org.

Users of Windows hosting do not need to worry about the maintenance of ASP servers. The cooling, security and power supply of IONOS's data centres meet the highest standards. In addition, we provide daily backups of your data with all ASP.NET hosting packages. With georedundancy, the performance of your ASP hosting will be stable even if physical problems occur on a server. For comprehensive data protection, users can rely on IONOS SiteLock, which checks your website and databases for malware, security leaks and other hacker attacks. After a completed scan, you can add the SiteLock certificate to your website to reassure your potential customers that your website is trustworthy. If you are using customer data on your website, IONOS also offers SSL certificates with the https security protocol. Phishing and SPAM security is also fully included, as well as 24/7 customer support with IONOS Windows server hosting.
