[patch] [cla] dojo/text without HTTP header "X-Requested-With"

[xMartin]

dojo.xhr sends an HTTP header "X-Requested-With: XMLHttpRequest" (#5801) to give servers a hint to send only partial HTML code as it is not a regular page request. Cross-domain xhr causes preflight request with this header (#9486) which can be prevented by setting this header to null. The loader plugin dojo/text uses dojo.xhr to retrieve text files like widget templates. It would be great if this worked cross-domain with CORS headers but it doesn't due to the preflight request.

Would it be reasonable to remove the header in the dojo/text plugin?

Patch attached, CCLA.

Fixed in [27536].

In order to use the feature, set the headers desired for the text plugin like this (e.g.)

  dojoConfig = {
    textPluginHeaders:null
  }

Works for me but in this case needs to be

textPluginHeaders: {"X-Requested-With": null}

Hey, This broke again when dojo/text.js was updated to use request instead of xhr

Will submit a new regression that references this ticket
