libURL: add to cache?

[David Bovill]

I would like to be able to add a local image to the cache. I can unload the
image to remove it, and I guess (thugh not tried I can save the image as a
file and then load the file: - but is there some way to add an image in
memory to the libURL cache?

I guess the short question is why add it to the cache?
If it is a local file, the access will be snappy, but if you want to
'preload', just put the image into a variable or custom property.

Then you have complete control over it as a binary file in either the
development environ (IDE) or as an appliction

The GUI i am working on is one which fetches a lot of stuff from the web -
images, thumbnails, data etc. To speed things up I am trying to create an
interface which loads stuff that may be needed into the background
(thubnails mostly) lowing the user to interact with the GUI.

Now I could script this all myself but the built in libURL cache does
prety well what I want - that is the scripts just refer to the data and
images by URL - if it has nt been downloded off it goes fetches it and
caches it in case the data is needed later. So far so good.

however if you have a situatio where a few hunder thumbnails are loading in
the background and the user clicks on the GUI to display a piece of text
information or to display a particular image you want to get that piece of
data straight away. This is where I get problems.

Firstly the blocking calls sometimes return empty due to ongoing loads to
the same domain (I think) and secondly once I have the image or data - Id
like to use the same code to display it later nd not write my own caching
malarky - duplicating what the internet library does - that is Id like to
add the image or data to the internet libraries cache so that as with the
rest of the data later calls to the url fetch it as per normal.
