c# - Call StaticFileHandler -


i have httphandler mapped aspnet_isapi.dll perform custom authentication check on static files (.pdf files) using iis 7.5 in classic mode:

void ihttphandler.processrequest(httpcontext context) { if(!user.ismember) { response.redirect("~/login.aspx?m=1"); } else { //serve static content } }

the above code works fine, except else statement logic. in else statement, want allow staticfilehandler process request, haven't been able sort out. suggestions on how "hand off" file iis serve request normal staticfile request, appreciated.

to answer question directly, can create staticfilehandler , have process request:

// serve static content: type type = typeof(httpapplication).assembly.gettype("system.web.staticfilehandler", true); ihttphandler handler = (ihttphandler)activator.createinstance(type, true); handler.processrequest(context);

but better idea might create http module instead of http handler:

public class authenticationmodule : ihttpmodule { public void dispose() { } public void init(httpapplication application) { application.authorizerequest += this.application_authorizerequest; } private void application_authorizerequest(object sender, eventargs e) { httpcontext context = ((httpapplication)sender).context; if (!user.ismember) context.response.redirect("~/login.aspx?m=1"); } }

c++ - Accessing inactive union member and undefined behavior? -

i under impression accessing union member other last 1 set ub, can't seem find solid reference (other answers claiming it's ub without support standard). so, undefined behavior? the confusion c explicitly permits type-punning through union, whereas c++ ( c++11 ) has no such permission. c11 6.5.2.3 structure , union members 95) if member used read contents of union object not same member last used store value in object, appropriate part of object representation of value reinterpreted object representation in new type described in 6.2.6 (a process called ‘‘type punning’’). might trap representation. the situation c++: c++11 9.5 unions [class.union] in union, @ 1 of non-static data members can active @ time, is, value of @ 1 of non-static data members can stored in union @ time. c++ later has language permitting use of unions containing struct s common initial sequences; doesn't permit type-punning. to determine whether union type-punning is allowe...

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.
