What is AspUpload Hosting?
AspUpload is a clever way of utilising HTML to reduce RAM and CPU load while uploading files to your server. AspUpload is a server component developed by Persits Software. More specifically it is a COM+ component, designed to enable ASP applications to upload files to your server from a browser window. The added convenience of using the HTML/browser approach also saves time.
The component allows you to upload files to your site while using a tiny amount of server resources. In some cases, as little as two lines of ASP script will suffice. Files are selected via an HTML tag. The component also includes a range of file management functions, such as saving files in databases, encryption, attribute management, image size extraction and so on.
Hassle-free browser uploads
AspUpload 3.x features include support for multiple simultaneous uploads, suport for large files (2GB to 4GB depending on platform), an HTML-based progress bar, directory creation and deletion, directory listing with sorting and more.
The latest version also introduces Unicode support, a new single Save method, additional object properties and of course performance tweaks aimed to reduce CPU and RAM load.
AspUpload also takes security into account, offering secure file downloading and encryption support. AspUpload is designed for Windows environments and runs on a wide range of current and obsolete Windows operating systems. IIS is another requirement and it should be noted that IIS 7 or later is necessary to support the latest features offered by AspUpload 3.x.
What about availability?
Most Microsoft hosting plans come with AspUpload support, so chances are you won't have anything to worry about if you decide to take the plunge. This is understandable as AspUpload does not impose any additional requirements on the platform. In fact, its primary goal is to reduce load rather than increase it - therefore hosts tend to like it.
Should you decide to purchase and install AspUpload, it shouldn't take up a lot of your time. The setup executable (aspupload.exe) will install the component (aspupload.dll) and all the documentation you will need to properly configure the component.
A comprehensive step by step guide is available online, so while you are downloading the installer, you may as well walk through the installation process. There is a catch though - AspUpload is not free, nor cheap. Most hosts support it though, on every plan, so you can add this popular component on your own, or have the host take care of everything, which depends on what sort of plan you choose (e.g. you can get AspUpload bundled in reseller offers, often at a substantial discount).
AspUpload security considerations
In a Web hosting environment, the administrator can disable certain features of the AspUpload component in an effort to bolster security.
It is important to note that all of these features are enabled by default, ranging from directory listings, file downloading, manipulating ACLs and so on. The features are disabled in the system registry by changing the corresponding values for each feature from 0 to 1.
- Parsits Software lists the following features as the riskiest ones:
- ActiveX registration. Using this feature, a malicious user can place a trojan-horse ActiveX DLL on the server, register and invoke it with simple ASP script.
- Directory Listing. This feature allows users to browser around the entire web server's hard drive and download any files.
- Account impersonation.
- File deletion and directory removal.
It should be noted that AspUpload relies on a numbef of different Perits Software components to unlock more functionality. For example, the AspEncrypt component must be installed to use file encryption.
Some of these components, such as AspEmail, are free, while others are not, so it is a good idea to check pricing and availability of other Persits components. Hosts usually tend to support all of them, but there could be some exceptions.
