asp.net - In iis, what does having multiple authentication types on the same app enabled imply? -

-

i've gone long telling myself, works i'll treat black box.

i can enable anonymous, forms, windows security, etc... if enable multiple of them on same path/app, mean? run? secure take role of verification?

is there point enabling anonymous , windows authentication?

is there way step through authentication process?

this article older versions windows server, logic same http://support.microsoft.com/kb/264921

when browser makes request, considers first request anonymous. therefore, not send credentials. if server not accept anonymous or if anonymous user account set on server not have permissions file being requested, iis server responds "access denied" error message , sends list of authentication types supported using 1 of following scenarios:

  • if windows integrated supported method (or if anonymous fails), browser must support method communicate server. if fails, server not try of other methods.
  • if basic supported method (or if anonymous fails), dialog box appears in credentials, , passes these server. attempts send credentials 3 times. if these fail, browser not connect server.
  • if both basic , windows integrated supported, browser determines method used. if browser supports kerberos or windows nt challenge/response, uses method. not fall basic. if windows nt challenge/response , kerberos not supported, browser uses basic, digest. order of precedence here basic, digest.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
