*WHEN I TRY TO select an image and sends i get.*
XMLHttpRequest cannot load
http://localhost:8080/_ah/upload/ahFwcmVjaXNlLXJheS05NDAwMHIiCxIVX19CbG9iVXBsb2FkU2Vzc2lvbl9fGICAgICAgIAJDA.
No 'Access-Control-Allow-Origin' header is present on the requested
resource. Origin 'http://localhost' is therefore not allowed access.
add-advert.html:183
HOW DO I HANDLE THIS?
My server uses the blobstore to handle the image.
I have even added the Access-Control-Allow-Origin on the server redirect
header but still i failed.
