contentDisposition

Defines the way a report will be presented:

inline: The browser will try to display the report results in the current browser window.
attachment: The browser will ask the user to save the report results or open them in a separate window (default).

With contentDisposition=inline a targetFrame has to be specified for the report to be displayed in, >> targetFrame.

Note: The browser's default behavior may overrule your contentDiposition / targetFrame settings, e.g. opening a report in a new tab instead of inline.
