VIDEO PLAYER ISSUE - UNITY 2017.4.0f1 - VUFORIA VIDEO DOES NOT PLAY WHEN THE URL (WEBSERVER) IS ASSIGNED VIA A VARIABLE

I am experiencing a very weird issue. The video player accepts the URL when directly assigned to it. Check below:

vidPlayer.url = "http://www.arcards.net/videos/VuforiaSizzle.mp4";

But, it does not accept the video when it is assigned via a variable. Check the code below. 'w' comes from a PHP file (via Jason). I'm using a web form.

When I print the url variable on the console it is perfectly printed without ANY errors. Please check the result below:

http://www.arcards.net/videos/VuforiaSizzle.mp4

url = w.text; url = url.Replace("\"",""); url = url.Replace("\\",""); vidPlayer.url = url;

  The Video Player is not accepting the URL via a variable. Please check the ERRORS below:

1) Player failed to load "file:///Users/benysebag/ARinvitationCard03/http://www.arcards.net/videos/VuforiaSizzle.mp4%0A%0A"

2) VideoPlayer cannot play url : http://www.arcards.net/videos/VuforiaSizzle.mp4

Please let me know if you have any hint for this issue to be solved. Thanks, Beny.
