ASP.NET Web Handler Format | Microsoft | Web Files |
The ASHX (ASP.NET Web Handler file) file extension is an integral part of the Microsoft.NET platform and is used for defining rules and abstracting code for .NET applications designed to run on web servers, such as IIS. It allows developers to define how requests are processed on the server side, as well as allowing them to customize their application logic to the given data context.
The syntax used to define the rules inside an ASHX file is derived from the same underlying language as that used by .NET. This means that it can also be used to call methods in other classes as well as allow developers to create their own custom functions and classes which can be exposed on the web to allow external access.
Structure and Technicalities
Structurally, an ASHX file is essentially an XML-based text document, with sections of code annotated by class and method names. The request processing begins by a root handler being assigned, which in turn either calls a method in an existing class or declares a new one inline. Furthermore, it has support for loading user-defined controls and additional options such as caching and headers.
In Comparison to Other File Formats
ASHX is very similar to other web-oriented file formats such as .ASPX, .ASMX, and ASHP, although each format has different strengths and weaknesses depending on the use case. It is important to select the right format for each situation depending on factors such as the desired level of control over the request or required customizability of code in order to get the best possible results.
Programs for WINDOWS system
Programs for MAC system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .ASHX) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .ASHX extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .ASHX file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .ASHX extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .ASHX extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .ASHX file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .ASHX file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .ASHX file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .ASHX file) will be extended to the maximum.
It is also good to check
- if the .ASHX file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
