ASP. NET and ASP programs prevent caching in IE

Source: Internet
Author: User


Microsoft Internet Information Server (IIS) allows you to use the following script at the beginning of a specific Active Server Pages (ASP) PageCodeEasily mark highly changeable pages or sensitive pages:

Response. cachecontrol = "no-Cache"
Response. addheader "Pragma", "No-Cache"
Response. expires =-1

ASP. NET program method:

Response. cache. setnoservercaching ();
Response. cache. setcacheability (system. Web. httpcacheability. nocache );
Response. cache. setnostore ();

However, this method has a major defect. After using it, all previous sessions will be cleared.

The HTML method is better:

<Meta HTTP-EQUIV = "Pragma" content = "no-Cache">
<Meta HTTP-EQUIV = "cache-control" content = "no-Cache">
<Meta HTTP-EQUIV = "expires" content = "0">
