Hi,
The load.ashx will check the request headers
If the header 'if-modified-since' is found , the load.ashx will return http status 304
And that not works for some cases.
The CuteEditorIgnore304 setting just disable to check the header 'if-modified-since'
So load.ashx will not return the 304 , and also will not cause that error again.
Regards,
Terry
