php - How to link external website to internal javascript page -


i have website lets call example.com , hosted @ external hosting provider. on site have page http://example.com/msg.php needs reference javascript intranet site lets running on example_intranet.com, have script reference like..

 <script src="http://example_intranet.com/js/messaging.js" type="text/javascipt">

i'm aware of cross-domain security issues , have setup necessary cors on example.com site , pages.

when visit http://example.com/msg.php outside company network (example_intranet.com) works expected, when visit same page within (inside) network page doesn't appear resolve javascript include ..

any suggestions on how fix this?that able have reference javascirpt work inside network.

i'm guessing dns issue, not code. intranet url domain resolves different "internal" ip address when on company network, , when outside resolves public ip address.

theoretical scenario:

when in company network, intranet url gets resolved local ip, 192.x.x.x or 10.x.x.x. when visit page on external host machine trying find javascript file using internal ip, might looking inside network of external host, , won't find it.

as experiment, try changing path javascript file use public ip of intranet url instead of domain name.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
