"NetworkError: 404 Not Found - http://tasks.arcgis.com/ArcGIS/rest/info?f=json"

Does anyone know what could be causing this error message in the ESRI JSAPI?

"NetworkError: 404 Not Found - http://tasks.arcgis.com/ArcGIS/rest/info?f=json"

In my case, I believe it is appearing through the use of the esri.tasks.Locator when the addressToLocations function is called.

Is there something wrong with my configuration somewhere? Although the task seems to run successfully.

I think that call is how the ArcGIS JS API determines if the ArcGIS Server supports CORS.

jacobsj,

I appreciate your response to my question. Thank you.

I have to say, though, that it seems odd one of the ESRI servers (tasks.arcgis.com) would have turned that support off (although certainly not impossible). Further, I tried making the same request to our ArcGIS Server, which is 10.1 and which the documentation suggests should have this support turned on by default. For that request, I get an HTTP error status of 500 (Internal Server Error).

Can anyone else comment on this question? If not, I'll just assume jacobsj is correct and ignore the error; but I'd prefer to be certain this is an acceptable (and ignorable) error. Are there others out there who are using the esri.task.Locator and getting the same error every time they invoke the address to Locations function?

Cheers

jeff is correct.  right now some esri servers support CORS, and some don't.

Okay, thank you!

I'll ignore the error, then.
