如何使用去除空格的 HTTP 模块?实现简单、干净且可重用...

How about using a whitespace removal HTTP module? It's simple to implement, clean and reusable...

与任何通用的空白删除解决方案一样，它可以通过删除需要的空白来轻松引入错误.不过用不了多久就可以试一试了.:-)

As with any generic whitespace removal solution though, it can easily introduce errors by removing white space where it is required. It wouldn't take long to give it a try though. :-)

这不适用于开箱即用的 .aspx 文件，因此您需要将 context_BeginRequest 更改为以下内容...

This will not work with .aspx files out of the box so you'll need to change the context_BeginRequest to the following...

void context_BeginRequest(object sender, EventArgs e)
{
    HttpApplication app = sender as HttpApplication;
    if (app.Response.ContentType == "text/html"
        || app.Response.ContentType == "application/xhtml+xml")
    {
        app.Response.Filter = new WhitespaceFilter(app.Response.Filter);
    }
}
