What technology is. ashx and. ashx used for CSS and JS loading?

{Code...} If you run css. ashx separately, the following message is displayed: css. ashx, js. ashx: Usage: css. ashx? HrefA, B, Cjs. ashx? Different files in the same directory of hrefA, B, and C are enclosed in square brackets. css. ashx? Href [AA1, A2] means connection ~ AA1.css and ~ A...

If you run css. ashx separately, the following message is displayed:

Css. ashx and js. ashx:Usage:

Css. ashx? Href = A, B, C

Js. ashx? Href = A, B, C

Different files in the same directory are enclosed in square brackets.

Css. ashx? Href = [A/A1, A2] means connection ~ /A/A1.css and ~ /A/A2.css

Js. ashx? Href = [B/B1, B2] indicates connection ~ /B/B1.js and ~ /B/B2.js

Hybrid usage

Css. ashx? Href = A, [B/B1, B2], C/C1 means connection ~ /A.css and ~ /B/B1.css and ~ /B/B2.css and ~ /C/C1.css

Processing of files not found:

If A. CSS is not found,/CSS Combiner file not found ~ /A.css/

If A. JS is not found, the // JS Combiner file not found will appear in the final output result ~ /A. js

What is the principle? Or is it a dynamic loading technology of. net itself?

It is a handler page. It means that the server is set up to process the resource file.

Href = [/public/autocomplete.css], [/index/global.css,header-top.css,header-logo.css,header-nav.css,footer.css,indexcontentv10.css]

Read multiple css codes in the background and return them to the foreground with an http request.

This parameter should be specially set to prevent browser caching problems.

& Compress

According to this parameter, the backend should read, splice, and compress all css files and return them to the foreground.

This can optimize the network transmission of resource files: 1. Reduce the number of http requests 2. Reduce the volume of css files

Tengine can be used to merge js and css files.

Please refer to this link http://msdn.microsoft.com/zh-cn/library/bb398986 (v = vs.100). aspx with detailed parsing.
In fact, the original aspx will also be registered as a hanlder by default. The difference between ashx and aspx is that aspx adds many components, attributes, and events for Development convenience, ashx is relatively low-level, so it is relatively simple and has the advantage of being fast.
In fact, this is not the case for ordinary customers. If we reinvent the wheel, we should adopt a third-party framework to compress Js and Css packages.
In addition, Asp. Net 4.5 has built in a framework such as, interested can see http://weblogs.asp.net/scottgu/archive/2011/11/27/new-bundling-and-minification-support-asp-net-4-5-series.aspx.
