Asp.net output overwrites the compressed page file instance

Example

The code is as follows:

Copy code

Using System; Using System. Data; Using System. Configuration; Using System. Web; Using System. Web. Security; Using System. Web. UI; Using System. Web. UI. WebControls; Using System. Web. UI. WebControls. WebParts; Using System.Web.UI.html Controls; Using System. Text. RegularExpressions; Using System. IO; /// <Summary> /// PageBase page base class /// </Summary> Public class PageBase: System. Web. UI. Page { Protected override void Render (htmlTextWriter writer)     { StringWriter sw = new StringWriter (); HtmlTextWriter htmlWriter = new htmlTextWriter (sw ); Base. Render (htmlWriter ); String html = sw. ToString (); Html = Regex. Replace (html, "[f v]", ""); Html = Regex. Replace (html, "{2,}", ""); Html = Regex. Replace (html, "> [] {1}", "> "); Writer. Write (html );     } }

Add several. net compression modules

1. WebResourceCompression compression module

This compression module is used to compress ASP in real time. all *. axd resources. Generally, when the aspx page uses ajax frameworks such as anthem.net or the asp.net verification control, axd file references are generated. This file is actually a js script. After this compression module is enabled, all axd resources are compressed by GZIP and then sent to the client. This module is especially suitable for projects where the aspx page applies the ajax framework or the large axd resource file needs to be referenced!

Use: decompress the package and place WebResourceCompression. dll to the BIN directory of the website project. In the Web. config Copy the code as follows:
<Add name = "WebResourceCompression" type = "WebResourceCompression. WebResourceCompressionModule"/>

Advantage: easy to use
Disadvantage: only ASP. NET2.0 or later versions are supported. Other resources except axd cannot be compressed!

II. PageCompression compression module

Unlike previous modules, this module is used to compress the aspx page. After this compression module is enabled, the aspx page will be compressed in real time, generally, kB of pages can be compressed to about 25 kb. This module is applicable to projects that only need to compress pages!

Use: decompress Compression. PageCompressionModule. dll to the BIN directory of the website project, and add the following statement to the Web. config Copy the code as follows:
<Add name = "PageCompressionModule" type = "Compression. PageCompressionModule, Compression. PageCompressionModule"/>

Advantage: easy to use
Disadvantage: only ASP. NET2.0 or later versions are supported. Other resources except the aspx page cannot be compressed. After compression is enabled, the axd resources referenced on the page will be invalid (BUG )!

III. HttpCompress6.0 compression module

This is an asp. net1.0/1.1/2.0 (versions earlier than 2.0 do not support gzip compression, only deflate compression), can compress all types of resources requested by the aspx page (MimeTypes, including images, js scripts, axd, aspx pages, and css files. in config, you can customize the types of resources to be compressed, the types of resources not compressed, or the specified pages to be compressed or not compressed, there are also powerful custom functions such as setting the compression ratio (high | normal | low). However, the most serious problem with this control is in asp. enabling compression in net2.0 will invalidate the axd file, so that if the ajax framework is applied on the page, the ajax function will become invalid.

Usage: omitted (similar to the CompressionModule compression module recommended below)
Advantages: open source code, powerful custom functions, support for asp. net1.0/1.1/2.0, can compress a variety of resources!
Disadvantage: complicated use. Enabling compression under asp. net2.0 will invalidate the axd file!
