Problem embedding pdf files in html

My website currently embeds pdf files. although resently, after a update or new gpo push, when i view the website in IE 9 or IE 8 the pdfs will launch in adobe reader independen开发者_如何学JAVAtly outside of the website verses within the webpage. Embedding works fine when i launch the site within firefox. the page loads currently with IE 7.

Any suggestions on how to troubleshoot this issue would be appreciate it.

By embedding what exactly do you mean? Within an iFrame or simply within the browser window? Does the url end with .pdf?

I believe your problem is linked with the HTTP headers being passed with the PDF - this usually allows you to request what the browser does with the file (Prompt for download, display in window etc).

You need to look at the Content-Disposition header - this article should put you in the correct direction.
