ION data reuse [message #28499]

Hi,

I would like to produce two images in an ION page, but use the same
dataset for each image. This dataset is large, and I only want to load it
once. Here is the current setup:

1) user fills out a form specifying lat/lon boundaries. Submit button
loads a new ION page

2) ION page loads lat/lon region from global file, displays. All this
happens in an <ION_IMAGE> tag

3) Repeat (2), but do some additional processing before displaying.

Since the exact same lat/lon region is read off disk in (2) and (3), it in
inefficient. Does anyone know how to load it only once?

Thanks,
-k.
