flyfishtom Posted December 2, 2016 Report Share Posted December 2, 2016 Hi, I am having a problem with CORS. When I test my server URL I get success. http://www.test-cors.org/#?client_method=GET&client_credentials=false&server_url=http%3A%2F%2F52.1.183.40&server_enable=true&server_status=200&server_credentials=false&server_tabs=remote When I test past the server URL I get fail. http://www.test-cors.org/#?client_method=GET&client_credentials=false&server_url=http%3A%2F%2F52.1.183.40%2Fadserver%2Fwww%2Fdelivery%2Fasyncjs.php&server_enable=true&server_status=200&server_credentials=false&server_tabs=remote http://www.test-cors.org/#?client_method=GET&client_credentials=false&server_url=http%3A%2F%2F52.1.183.40%2Fadserver&server_enable=true&server_status=200&server_credentials=false&server_tabs=remote Does the adserver have any unique cors settings?

flyfishtom Posted December 7, 2016 Author Report Share Posted December 7, 2016 Has anyone seen this error before? Is there a setting in Revive Adserver to fix this? It seems to be coming from revive code. XMLHttpRequest cannot load http://52.1.183.40/adserver/www/delivery/fc.php?script=bannerTypeHtml:vastI…3D3&nz=1&source=&r=R0.05822725687175989&block=1&format=vast3&charset=UTF-8. A wildcard '*' cannot be used in the 'Access-Control-Allow-Origin' header when the credentials flag is true. Origin 'http://www.megabitllc.com' is therefore not allowed access. The credentials mode of an XMLHttpRequest is controlled by the withCredentials attribute. Quote Link to comment Share on other sites More sharing options...
andrewatfornax Posted December 13, 2016 Report Share Posted December 13, 2016 Hi @flyfishtom, I don't think there are any settings in Revive Adserver to fix this, but it is potentially a bug. I've just dropped an email to one of the other developers who knows more about this than me, to see if it is... Quote Link to comment Share on other sites More sharing options...
andrewatfornax Posted December 18, 2016 Report Share Posted December 18, 2016 Hi @flyfishtom, This definitely looks like a bug to me - but my colleague has pointed out the &format=vast3 part of the URL. This isn't something that Revive Adserver does - so, I am assuming you are running a 3rd party plugin or have applied a patch? Quote Link to comment Share on other sites More sharing options...
flyfishtom Posted January 5, 2017 Author Report Share Posted January 5, 2017 Sorry for the delay. Yes it's a third party vast 3.0 plugin. I'll follow up with the developer. Thanks for looking at it. Tom Quote Link to comment Share on other sites More sharing options...
flyfishtom Posted January 5, 2017 Author Report Share Posted January 5, 2017 (edited) Andrew id the Revive server setting credentials to true, possibly for setting a cookie ? Also, nowhere on my Apache Revive server or my Apache web server am I setting Access-Control-Allow-Origin to "*" so I'm curious if Revive is doing this. As a result of this I am not able to get Banner Delivery Capping to work. I can enter the caps in the UI but the ads don't play once I set the caps. I think the cookies aren't working. When I set the Campaign to "Show capped ads if cookies are disabled " the ad plays but it doesn't use the caps I set, it plays every time. Tom https://github.com/whatwg/fetch/issues/251 .

andrewatfornax Posted January 5, 2017 Report Share Posted January 5, 2017 Hi @flyfishtom, I'd have to dig to find out if Revive Adserver is doing this - but does it work when you are not using the 3rd party plugin? If so, then that would narrow down the setting of the headers to the plugin. Quote Link to comment Share on other sites More sharing options...
firstimpression Posted January 17, 2017 Report Share Posted January 17, 2017 As a temp walkaround: if you use nginx as frontend you can add headers in nginx host config. andrewatfornax 1 Quote Link to comment Share on other sites More sharing options...
