问题描述

What are the differences between PostBackUrl,Response.Redirect and Server.Transfer? What method we need to follow in which situations?

推荐答案

PostbackUrl更改表单的 action 属性，因此初始页面不会更改，但是当用户发布表单时，会将其数据发送到不同的页面.

PostbackUrl changes form's action attribute, so initial page is not changed, but when user posts the form, it's data being sent to the different page.

Response.Redirect导致 HTTP 302重定向.这是常见的重定向操作，与 301重定向不同，在您要完全更改网址时使用并永久地.

Response.Redirect leads to HTTP 302 Redirect. It is the common redirect action unlike 301 redirect which is used when you want to change the url completely and permanently.

Server.Transfer不会激活任何HTTP请求，并且对用户完全透明.通常，它用于显示错误页面(例如404或500个HTTP状态)，因为如果使用重定向而不是Server.Transfer，则浏览器(如果是搜索引擎搜寻器，则更重要)将不会收到原始HTTP状态(例如404)).

Server.Transfer in fact does not activates any HTTP requests and completely transparent to user. Usually it is used to show error pages (e.g. 404 or 500 HTTP statuses), because if you will use redirect instead of Server.Transfer, browser (more important if it's a search engine crawler) will not receive original HTTP status (404 for example).
