two. The four big new character of ASP+
1. ASP+ is based on brand-new framework
ASP+ is the frame when be based on NGWS completely to move.
The frame when NGWS moves (the core component that NGWS Runtime Framework) is the.NET framework that the range that Microsoft offers is down generation Web.A kind of brand-new rock-bottom foundation framework that is aimed at Windows is when NGWS moves,It is located in Windows move and between user program,Be used to the execution that manages code.It offers a kind to enclose between developer and operating system,Make Windows process designing becomes more simple.When NGWS moves, be complete be based on an object,It expanded COM(Component Object Model,Package object model) structure,To can expand distributed application process offerred more new buildup the gender serves.When having NGWS to move,Our or else needs to forget to clear of a certain object in ASP+ page concern,Because it is met,rubbish of automatic processing memory reclaims.The visit of the rock-bottom service with a few pairs of crucial at the same time operating systems also becomes more relaxed,Security,Attestation,File system is visited,Network news,Wait a moment etc...Everything is unchallenged!
2.ASP+ is carried out through compiling
ASP+ made a lot of improvement in the light of the executive expression of ASP,Page script is carried out no longer through the explanation,Pass NGWS(Next Generation Web Services however,Next generation Web serve) compile compatibly implement compile will carry out.Do not misunderstand!We indicate compiling is not to want you to make.EXE file.
You still mix to write code euqally before,When compiling the job to move by NGWS when script code first time receives a request and moving finish automatically,The copy that saves a cache at the same time.Receive a request again when script when,The copy that the system moves cache directly,Implement rate quickly substantially greatly thereby,What move now because of us is the code that the course compiles.
if source script had alter,The meeting when moving discards automatically to compile version oldly from inside cache,So that be received next time,code is compiled afresh when executive request.
3. Data cache technology
became good,We had a faster ASP+ that has compiled now,But this is insufficient still.Imagine such scenario:The ASP+ page that you have a trends to generate,The content of this page results from database of a tiring-room,And this database is likely several talents are able to update...Now,Assume your server received a request that comes from client end,The server can establish link with the database,Executive inquiry,Resumptive record,Feedback gives an user,Very simple,Right?But become,the server should be handled in same time by tens of thousands identical request,The consequence with meeting what kind of generation?Without doubt,The systematic natural resources that is meaningless repetitive operation and dreariness as a result takes up.
Why should this use to data cache technology namely.
