"ASP. NET 2.0 secrets" Reading Notes (4)

* MIME: Baidu encyclopedia, which is the multimedia type of the notification browser.

* ASP. NET: The execution user. In 2K3, It is the network service, and other systems are the ASPNET accounts.

* Store files in the database: It's very simple. Let's not talk about it. p124

* Delivery file: p127, directly in context. response. binarywrite (bytes );

* Maxrequestlength: It is often referred to as the 4 MB limit. To transfer a file larger than this limit, you must modify this parameter. Otherwise, an exception is thrown, but this parameter is not completely modified, next, let's talk about the following items.

* Lengthdiskthreshold: As it literally means, it aims to solve the limited memory for uploading files with a relatively large memory. In 2.0, its default value is 80 KB, the part that exceeds it is cached in the file system. Of course, this value is smaller than the one above,

*. Write (@ buffer, null, 0): When writing data using this clause, the buffer size is preferably 8040 bytes (recommended by Microsoft)

* Commandbehavior. sequentialaccess: This method can be used to stream read data. It is best to set it to 8040 bytes for reading. It is a memory and can be left empty.

* Disable caching when outputting large files: Same as above. When the file is divided into 8040 bytes, It is not stored in the server memory.

* Textptr (): This is used by databases before sql2005, instead of the Write statement;

* Application: the previous ASP object can be replaced by a static object and placed in global. aspx, which is faster and has no process problems.

* Write down the two books we saw today, ". Net security programming" and "Visual Studio hacks".

* Wizardstep-steptype: it is very important to control the current type and must be customized.
