How to open save dialog box instead of file getting opened in browser for my Sharepoint site

Question

My site is developed in SharePoint 2010.
In my Testing site,
<a href="file.pdf" target="_blank">Download File</a>

when click on the above a tag, file opens directly in browswer(IE/Chrome/FireFox)

But same a tag is used in my Live site where it ask to save file(In IE) or gets downloaded(in Chrome).

Answer 1

For link on file use standard SharePoint download.aspx page.

<a href="http://yourSite/_layouts/download.aspx?SourceUrl=http://pathToFile" target="_blank">Download File</a>

Download.aspx will read the content of the file you send as the SourceUrl, and render it back to you on the HTTP response.

Hope that helps
