Managing trust policy in pdf

[Nina_Storm@adobeforums.com]

In an interactive pdf using Acrobat 7 or newer you wil be prompted for
permission as you click a weblink:

<http://home19.inet.tele.dk/storms/trust_policy.png>

I wunder if it is possible to create a Document property which will
embed permission for specific URL access or even all URL access not
showing this pop-up prompt?

I tried, but did not succeed:

<http://home19.inet.tele.dk/storms/property.png>

Can you guide me if this is possible?

The prompt does not show up if the pdf itself generated the weblink from
a written URL for instance in InDesign CS2.

There are people who know a lot more about the deep security settings in Acrobat. I find them incredibly opaque and confusing.

Nevertheless, I think the place where the settings needs to be set is Acrobat > Preferences > Trust Manager. In Acrobat 7, it appears that if you click on the button Change Site Settings at the bottom of the dialog to open the Managed Sites dialog, you can choose Default Behavior for URL access: Use Trust List, or Always Allow. Always Allow is probably a little dangerous, but it looks like you can enter the ULR in the Trust List and set it to Allow.

Another way of answering your question is that you couldn't set that property in a document. That would be incredibly dangerous because multimedia could embed a virus or other malware.

The user needs to be able to determine what they consider to be a "trusted" document based on the source it's coming from.

Thank you Steve, I realise that I can set my own preferences to "always
trust" in the Trust Manager, and I admit that it should be up to the
user to determine what to trust in their personal preferences. But...

....If you create an interactive pdf and distribute it to customers to
perform as smooth as possible, this behaviour seams to be disturbing.
Performing similar presentations from other applications/browsers does
not imply similar warnings if you click another URL (no multimedia
involved).

Furthermore the warning does not show up if the pdf itself generated the
weblink from a written URL in InDesign CS2. If you in editable text just
write for instance [url]www.google.com[/url], without creating manually a
hyperlink, export a pdf with interactivity and hyperlink checked it wil
create a link which does not prompt for permission.

This made me suppose that it is possible to apply the same behaviour to
other intendedly applied weblinks.
But I now notice that interactive magazines like "Proxy",
"InDesignMagazine" and "GX magazine" all have the same pop-up prompting
behaviour, so I guess my assumption is wrong - it cannot be done.

You're correct. Security wins.
