ALHow to check if WFileResource is not used anymore?

Added by A L over 6 years ago

Hi,

I have a WFileResource that is created on demand,
and downloaded with

wApp->redirect(fileResourcePtr->url());

Now I would like to delete it, when no longer needed.
But after reading twice the documentation
of WResource hierarchy, I have no idea how to
check if e.g. WFileResource has been already downloaded
by the client. Is there a way to do this?

Thanks and best wishes,
Adrian

That's indeed not something WResource keeps track of by default. You could hook into handleRequest() to see if that's been called. Note: don't try to delete the resource in handleRequest(). You'll have to defer the deletion.

OK, thanks --- I'll try to this.
BTW, Wt is great.

Best wishes,
Adrian
