After surfing the internet, we regard information as knowledge, favorites as learning, reading as thinking, and storage as mastery. Like a chestnut who collects nuts in the fall, he fills up his reader and hard drive, but still feels hungry and impatient.As a result, some idiots said with emotion: sodesnaes, the Network has made people impetuous. I rely on it, I rely on it, I fly on it, where is it? I have described a common phenomenon in which people

HttpModule, and then finally handles the corresponding file in HttpHandler.The essence of HttpModule is in the different stages of application events. Perform different processes, such as validation, calculation, change, and so on.HttpModule is very easy to write. Just need to integrate the IHttpModule interface to be able, note is to write a class library program, and then the Web. config in which the register, a major HttpModule is finished.Session interface, can have an interface. This allow

regex. It can be used either through the ' RegExp ' constructor or with a forward slash (/) to encapsulate the matching model.Regular expression constructors:Grammar:New REGEXP (pattern[, flags]);Example:var New REGEXP (' abc ');the original ecological regular expression :Grammar:/pattern/flags;Example:var regexliteral =/abc/;? The flags here are optional and I will explain them later in this article. In some cases, we need to create a dynamic regular expression, when the original ecology is no
