iFrame suppress authentication popup for https when parent window is already authenticated

Question

I've developed a print mechanism for an intranet application running over HTTPS. Using javascript and jQuery I create an iframe in the page and populate it with all the dynamic data that should be printed.

The iframe has a source of /MyController/Print which just returns a blank dummy page. This is then replaced with the dynamic content. I do this to avoid having the page location be "about:blank" on the print outs and to get a popup about some secure content, some insecure content.

This works great locally, but once it's on the https server I get a domain authentication popup when trying to create the iframe. It's asking for my username and password (even though the main application never does --- it uses the internal network to identify users).

Is there some way to suppress the user/pass popup?

Answer 1

Using iframe in this kind of situation usually creates x domain security issues.

This issues are happening according to Same Origin Policy

Therefore the recommended workaround for this matter would be for you to use

<style media="print">
   css properties to modify the page for print
</style>

Answer 2

this is actually from another post but i really like the solution.

you can set your action controller to compose your printable data as pdf

public FileStreamResult Print(int id)


{
     var model = _CustomRepository.Get(id);
     this.ConvertToPDF = true;
     return View( "HtmlView" );
 }

 public override OnResultExecuting( ResultExecutingContext context )
 {
      if (this.ConvertToPDF)
      {
          this.PDFStream = new MemoryStream();
          context.HttpContext.Response.Filter = new PDFStreamFilter( this.PDFStream );
      }
 }

 public override OnResultExecuted( ResultExecutedContext context )
 {
      if (this.ConvertToPDF)
      {
          context.HttpContext.Response.Clear();
          this.PDFStream.Seek( 0, SeekOrigin.Begin );
          Stream byteStream = _PrintService.PrintToPDF( this.PDFStream );
          StreamReader reader = new StreamReader( byteStream );
          context.HttpContext.Response.AddHeader( "content-dispostion",
                 "attachemnt; filename=report.pdf" );
          context.HttpContext.Response.AddHeader( "content-type",
                 "application/pdf" );
          context.HttpContext.Response.Write( reader.ReadToEnd() );
      }
}

I am assuming you are using .net mvc. I hope im not wrong
