c# - Change originating IP - circumventing caching of connections -

-

i need call same api many times, different ip's based on parameters.

i've implemented code in question: how change originating ip in httpwebrequest

this worked when needed specify single ip api calling, need use several ips based on requirements, , method no longer seems work. api url seems cached , subsequent calls use ip, instead of specific 1 wish set on every call.

i need method let me choose source ip each request.

adding:

if split application 2 separate apps, each 1 using own source ip, brute force approach force work? in other words, caching performed per process? (i assume so).

using httpwebrequest.connectiongroupname should able around servicepoint connection reuse.

var hr = (httpwebrequest)webrequest.create("http://google.com?"); hr.connectiongroupname = hr.requesturi.tostring(); //different connection pool per url. might better make random. hr.getresponse();

alternatively can force close group using servicepoint.closeconnectiongroup. default group null.

var hr = (httpwebrequest)webrequest.create("http://google.com"); hr.servicepoint.closeconnectiongroup(null); hr.getresponse();

i have php code pulls info database. uses prepared statement, works fine written below: <?php $n = '5'; if ($stmt = $connection->prepare("select title items id = ?")) { $stmt->bind_param("s", $n); $stmt->execute(); $stmt->bind_result($title); while ($stmt->fetch()) { echo $title; } $stmt->close(); } ?> and let's echo "batman". however, when move placeholder here: "select ? items id = 5" and change: $n = 'title'; instead of echoing "batman", echoes "title". not possible use placeholder select parameter? what have done this: select "title" items id = 5 you cant use prepared statement bindings identifiers, parameters.
