.net - WCF Security across multiple services -


we moving our old .net 1.1 remoted system .net 4.0 wcf architecture. part of system desktop client app using call 300+ functions sit on our middle tier.

we consolidating these remotable functions 9 services need way verify user has first performed "login" function before other subsequent wcf calls.

since login happens on 1 of these services, not sure if there way "federate" across services. (all hosted on same machine, same domain.) exposing services on net.tcp goal of allowing wshttp binding external clients in long run. (not sure if different binding might help)

what i've come host singleton holds authentication info. when user login verified , submitted "security store" return guid client send subsequent wcf calls.

and each wcf call validate against singleton "security store".

so question is... can use native wcf accomplish same goal?

this table secect binding enter image description here

about security, wcf has several types auth, securitymode

ask particularized, security in wcf big topic

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.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
