Caching on the embedded widget

[Akbar Hossain]

Hi,

I was wondering if it is possible for the caching of FOAF files when
displaying the VIX widget to be switched off by the caller?

Thanks

Yes, it's possible, but not recommended for the production use.
If you need it for testing purposes (but not *a lot*),
then just add "&nocache=1" to the path:
http://foaf-visualizer.org/embed/widget/?uri=URI&nocache=1

Without caching, FOAF.Vix needs to fetch a remote
URL each time you call it, so the performance drops heavily.

BTW, an important thing:

This won't work as you would expect:
...embed/widget/?uri=http://webid.myxwiki.org/xwiki/bin/view/XWiki/
hjs#me
Instead, call it this way:
...embed/widget/?uri=http://webid.myxwiki.org/xwiki/bin/view/XWiki/
hjs&hash=me

For this particular case, there won't be any difference,
but it might for other. Just convert "#foo" into "&hash=foo".

PS You can also add nocss=1 and specify a custom CSS yourself
or overwrite the default stylesheet.

Regards,
Wojciech

Hi

Thanks for the tips.

I will make sure we urlencode the webid.

I am wondering if perhaps rather than switching off the cache if we
basically want to allow the user to force a refresh.
So the user interaction is view the widget via the cache and if the
think its out of date a press a refresh now button/link. The link
being on the widget or on the hosting page.

Thoughts?

Thanks

Using nocache=1 means also a refresh.

FOAF.Vix's cache lifetime is only 48h. Do you really find it
to be too long? Most FOAFs don't change often so I think it's
okay.

Okay thanks. The issue is that people are editting thier foaf files on
foaf.me on the data tab or with webdav / tabulator. Flick to the me
tab. And think the edit hasnt worked.

I will see what we can do to minimise any nocache usage. We know when
they have editted a profile on foaf.me

Thanks again.
