Answer 1

Setting the content-disposition and content-type headers should do it, but you might also need to call Response.ClearHeaders() to clear other headers that have been set.

Also, try using Fiddler to see the actual headers and content from the response and compare them to those from a site that works like you want.

Here is an article on using the embed tag to do it:http://blogs.adobe.com/pdfdevjunkie/2007/08/using_the_html_embed_tag_to_di.html

Answer 3

If you have the budget, my company sells a set of products that includes an AJAX based image viewer that will let you view the PDF pages in line without Acrobat at all. In its simplest form, it is just a viewer, but you can layer in interactivity as you need.

Answer 4

If you are using an ashx (web handler) try this:-

context.Response.AddHeader("content-disposition", "inline; filename=Something.pdf")

Answer 5

I think this header will do what you want

Content-type: application/pdf

Since you say that is not working, then I suspect it is a configuration setting on the client side.

Check your installed version of Adobe Acrobat. There is a setting in preferences for "Internet" and a checkbox that says "Display PDF in Browser".

Answer 6

OK, turns out it was a stupid question, but I'm glad I asked it because I had never heard of Fiddler (which led me to the answer, which is why I'm accepting tspauld's answer). The PDF is generated by a web service that serves the file to a couple of different front-end sites. I was setting the content disposition to inline in the service, but that didn't matter, because the browser never got that header; it got the header from the front-end site (which was attachment). I changed it in the front-end site and that fixed it.

So the answer is that you have to have Content-Type=application/pdf and Content-Disposition=inline; filename=Something.pdf, as others have said.
