Two HttpServletResponse Responses?

[Charles Swanson]

How do I send two HttpServletResponse responses? I'm writing an app where I save a file to the user's PC and then redirect them to another page. I can save the file or redirect, but not do both. Here's my code:

try
{
	FacesContext context = FacesContext.getCurrentInstance();
	HttpServletResponse response = (HttpServletResponse) context.getExternalContext().getResponse();
	      
	response.setContentType("text/xml");
	response.setHeader("Content-Disposition", "attachment;filename=\"" + FILE_NAME + "\""); 
	
	OutputStream outStream = response.getOutputStream();
	outStream.write(strFile.getBytes());
	outStream.flush();
	outStream.close();
		
	response.sendRedirect("http://www.google.com");
	
	return SUCCESS;
}
catch(Exception e)
{
	strError = "Error: Could not save file.";
	return FAILURE;
} 
 

If I leave it as-is, it will redirect to google without saving the file. If I comment out the redirect line, the file saves as it should.

Is there some way to make both work?

You can only send one response.

I kinda figured as much. Thanks for the confirmation.
Any easy ways around this? Or will it just be a "fun" little problem solving mission for me?

It's not clear exactly what you are trying to accomplish by redirecting to google. If you were redirecting to something within your own app, that'd be different.

[Charles Swanson]

Sorry, I should have mentioned the google URL was just a filler. The actual app would redirect to another page within the site.

[Bear Bibeault]

Try not to do that. Using "filler" in this case, creates a completely different environment for the question.

Generally, things like this are accomplished by redirecting to the next page first, and having JavaScript on that page that initiates the request that performs the attachment download.

[Charles Swanson]

Unfortunately, I'm unable to use JavaScript. The site this will be hosted on has a policy against using JavaScript (which has made the project more difficult than it should be... it's a longer story, but in the end I was told no JavaScript, so I went with that.)

[Paul Clapham]

Well, you certainly aren't going to be able to do that without some Javascript somewhere. So I guess your project sponsors are just out of luck there.

Ah yes, denying carpenters their saws.

Haha, exactly. It's actually been a semi-entertaining challenge to build this thing without any JavaScript. It's certainly created some large and ugly code though...
Thanks for the help guys... at least I won't waste too much time finding a non-existent answer.
