[opencms-dev] URL fingerprinting

[Paul-Inge Flakstad]

Hi Stephan,

After having read Stephan H.'s reply just now, I'd say this is exactly what I had in mind.

Would you be able to describe in short how you went about it?

I think this approach (appending a date-last-modified-parameter) should actually be the *default* behavior for OpenCms. Configurable, of course, so one could turn it off it needed. :)

Cheers,
Paul

Hey,

we used to simply override the Link-Tag and append the date modified as query parameter. This way opencms will generate an unique URL for every published version.

But this would be a nice feature to have in general ;)

Hi,

Has anyone considered URL fingerprinting in OpenCms?

I'm Curious because I'm thinking about modifying the export/link handler (?) to manage this. Since it's already doing some modification to the URLs, it should be possible to extend that some more - right ..?

What I have in mind is adding the fingerprint when exporting (similarly to how /opencms/export/ is injected).

E.g. if the VFS resource's offline URL is
/static/my.css
the online URL would become
/opencms/export/static/my-32819023810832091.css
when requested online.

Same for images, javascript and whatnot.

With fingerprinting in place, one could set the appropriate headers in Apache (or whatever's in front) and ta-daaaa pages would load (possibly a lot) faster, because many resources would be cached client-side.

Would sure like to hear your thoughts on this, if you have any.

(Don't know about URL fingerprinting? Then you should read this: https://developers.google.com/speed/docs/insights/LeverageBrowserCaching)

Cheers,
Paul
