, they are not contiguous in the IIS log, and you cannot accurately count on user requests. For example: A1.aspx with iframe embedded b1.aspx, b2.aspx, b3.aspx, when you count a1.aspx load time, you get the results will always be different from the user feel, Because A1.aspx's timetaken does not contain b1.aspx, b2.aspx, b3.aspx these three requests timetaken!Therefore, if you want to use IIS logs to analyze program performance, the IFRAME will not be used again.Reprinted from: http://www.cnblog

calculated first, the right result 3 is assigned to A; You might say this is the operator's priority. In fact, what this article wants to express is that the assignment operation is to assign a value to the left on the right of "=". The following example should help you understand more.1 var A, B; 2 a=b=1+2;Which follows the right combination of the assignment operator:A = b = 1 + 2 equivalent to a = (b= 1+2)where b equals the return value of 1+2 3;A equals the return value of b=3 3;

Operation DemarcationIn the design of the WCF operation contract, sometimes there will be a number of calls in the order of the business, some operations can not be called first, some operations must be last called, such as in a box to take out a thing, you must first do open the box operation, and the closing of the box should be done after the completion of all

requirements, I want to retrieve the results of a =1 or b=1 and c = 0 or c=1Example:SELECT * FROM Test where a = 1 or b = 1 and (c = 0 or c = 1)This retrieves the result set of A=1 or b=1, and then filters out the results of c=0 or c=1.If we change the wording of theSELECT * FROM Test where a = 1 or b = 1 and c = 0 or c = 1This retrieves the result set of a=1 or B =1 or c=1, and then filters out the results of the c=0, which is not what I expected, so it is OK to adjust their processing
