Is it possible to add 2 distinct Content-Disposition headers in the following way

Question

 oResponse.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(fileName_DBText, Encoding.UTF8).Replace("+", "%20"));
 oResponse.AddHeader("Content-Disposition", "inline=" + HttpUtility.UrlEncode(fileName_DBText, Encoding.UTF8).Replace("+", "%20"));

The above was causing me an issue in Chrome only. No issue in IE or Firefox. Removal of the 2nd AddHeader (adding the inline directive), resolved the issue. I was under the impression that adding both was fine and the browser would work out what to do. Anyone have a definitive answer on this?

Answer 1

a) no, you can't have multiple ones.

b) the syntax for the second one is invalid; "inline" doesn't take a parameter.

c) "inline" and "attachment" are contradictory; what are you trying to achieve?

(the spec is RFC 6266, btw)

Answer 2

Solution was very straightforward: Simply removed the following line of code -

oResponse.AddHeader("Content-Disposition", "inline=" + HttpUtility.UrlEncode(fileName_DBText, Encoding.UTF8).Replace("+", "%20"));

As @Julian Reschike stated, you cannot have multiple content-disposition headers, which I wasn't aware of. In any case, the syntax of the above line was incorrect as I had it. Line removed and everything back to how it should be.
