Topic: Share link is not a perma-link

When will you have perma-links implemented?

Exactly what are you expecting, Joscelin?

I would expect that for every http://photosynth.net/preview/ URL today, the only difference in the future will be the removal of the "preview/".
In other words: 
http://photosynth.net/preview/view/943fb8c3-e7fd-4d48-adf3-322b75ece294 (Preview link) will in future be redirected to: 
http://photosynth.net/view/943fb8c3-e7fd-4d48-adf3-322b75ece294

This is because Photosynth already uses a page handler to deliver the appropriately formatted page to different devices.

For example, if I link to a stitched panorama's old view.aspx or embed.aspx URLs, anyone who is using a mobile device like Windows Phone 8, Windows RT, iPad, or iPhone will be redirected to the /view/ URL for the HTML5 panorama viewer. In other words, this URL: 
http://photosynth.net/view.aspx?cid=cb77e8f1-2e25-4de2-98f2-7e9a12d5eac3 (Desktop link) will get redirected to: 
http://photosynth.net/view/cb77e8f1-2e25-4de2-98f2-7e9a12d5eac3

This began to be the case not long after the launch of Photosynth's mobile panorama app for iOS.
See Steve Glenner's reply to me here from April 2011: http://photosynth.net/discussion.aspx?cat=01b6f15f-42eb-49cb-a221-ed56615e1c47&dis=7005372a-728f-4742-a952-b81b30722d8e

Also noted toward the end of my old request for simpler URLs: http://photosynth.net/discussion.aspx?cat=01b6f15f-42eb-49cb-a221-ed56615e1c47&dis=75b9272d-02c3-4d8d-9b28-0563b65eb582
(By the way, thanks Adrian and Photosynth team in general for listening on profile and view pages.)

An older example is that when Photosynth's Silverlight viewer was in beta ( http://bit.ly/psbslvb | Archived 'About' page: http://bit.ly/pssvb ), you actually had to navigate to http://photosynth.net/silverlight (Archived: http://bit.ly/pslvb ) and manually paste in the normal view.aspx URL of a synth to a form on the page to attach the synth's collection ID to the end of photosynth.net/silverlight/photosynth.aspx?cid= (or at least start with the Silverlight URL for a synth and copy your synth's collection ID from its view URL to replace on the existing link).

Example: 
Normal view link: http://photosynth.net/view.aspx?cid=1a012e5b-f88f-481f-ab3e-98f32c36665e (used to use the Direct3D viewer)
Silverlight beta link: http://photosynth.net/silverlight/photosynth.aspx?cid=1a012e5b-f88f-481f-ab3e-98f32c36665e

For some time after the Silverlight beta, these limited time URLs would redirect to the collection's view.aspx page.
(P.S. Photosynth team, they don't anymore.)
Well right, it is that obvious that a url containing 'preview' is not a permanent one, that I did not think about explaining it.

I would expect a url to be valid eternaly with the Photosynth opening in an appropriate viewer, be it an app or a webbrowser.

If you copy the link to any of your preview synths from your profile on the main site http://photosynth.net/userprofilepage.aspx?user=Joscelin.Trouwborst you'll notice that they don't have the preview/ in the URL and that the page handler is forwarding you to a URL with the preview/ directory injected, so I see no reason why the inverse wouldn't be done in the future.

I'm sure that the Photosynth team won't allow all the links and embeds shared during the Tech Preview to suddenly break after they relaunch the completed new site to replace the old.

When the preview site is finished and replaces the main site, then the preview/ will be taken off all URLs and anyone getting a share link from then on will be given one without the preview/ included and anyone clicking a link with the preview/ in it from these days will get automatically redirected to a URL without the preview/.
NateLawrence (6 months ago)
All I'm saying is I think that your expectation that a photosynth URL remain valid in the future is valid and that I expect that any link you share to a preview synth today is already permanently useful and will continue to send people to the intended synth after the preview/ in the site's links is removed.
So far I have been using the share link of the preview site :-(
PhotosynthTeam (6 months ago)
When we exit this "preview" stage, we will make sure that all URLs that contain "preview" will continue to work. Nate is correct.
Relieved :-)
