In ASP+ ,When server first time from inside the database after resumptive data,Data is saved in variable,After the server receives identical request,The data that passes cache delivers a client to carry from the server directly,We need not disturb surely now database.

　 　 of course,The cache time limit that you must set destiny to occupy in code,The time that arrived to set or contented and specific requirement,With respect to clear empty cache,Resumptive new data.As to how to come the deadline of set cache,Depend on completely your demand and skill.

　 　 4.ADO+ ,More the ADO that uses easily

　 　 good horse matchs good saddle,Microsoft is in roll out ASP+ while,Also rolled out brand-new ADO,Namely ADO+ .ADO+ with dimension of a kind of N (of N-dimensional) ,Object-oriented means will process data.In ADO,Data comes out with planar form expression,Go namely,Row.But if there is a specific cavalcade itself in RecordSet,be a RecordSet,Form a new dimension to spend thereby?Such case is very stubborn in ADO,And found with ADO+ such multidimensional the fatigue that RecordSet is raise one's hand only however.

　 　 in fact,The RecordSet that says above is in ADO+ already not answer existence,Those who replace is DataSet.In ADO+ ,The gather that DataSet is equivalent to RecordSet,DataView is similar to RecordSet.

　 　 three. Server end accuses

It is good that another of 　 　 ASP+ inviting place increased more namely used server end accuses,The feedback that Microsoft listened to Web developer well apparently,Add newly control a function that enhanced ASP+ not only,Will let developer before at the same time people a lot of trival reduplicative jobs that have a headache give accuse went finishing.It is to be opposite these accusing below classify roughly:

　 　 1.List Controls

　 　 accuses this kind list is founded to become more relaxed and simple in making you carry a browser in the client,Give you at the same time more but custom-built sex,You can spend fewer energy to go up in page layout now.Example has:Repeater, dataList and DataGrid Controls

　 　 2.Rich Controls

　 　 accuses this kind be used to in the client end is generated more complex,Rich HTML element.Be like:Calender Control

　 　 3.Validation Controls

　 　 test and verify accuses belong to concealed type to accuse,They are used to executive client end and the test and verify that the server carries.This kind accuses what the amount comparatives is much,Can finish the job of sundry test and verify that needs to write code by hand before,Programmer is OK now the If with many leave out. . . Else statement.Be like:RequiredFieldValidator Control, compareValidator Control, rangeValidator Control, and RegularExpressionValidator Control
