Graphics

I've written a web service that generates an image based live data.

In expression, we can assign the image a link, like http://myserver.mycompany.com/generate_image?id=1

The problem is that once Xpression gets the image, it doesn't seem to want to update. If I type the URL directly in a browser, I always see the latest version of the image, but in Xpression, I always see the image as it was the first time Xpression grabbed it.

In other words, it seems like it's caching the image. That's actually OK, since it takes a long time (up to five seconds or so) for the server to return an image (it's built using a fairly complex set of data and calculations), but we need to be able to periodically force it to update. Is it possible?

This might work for you, but it might not, try it and let us know:
Studio > Edit > Preferences > In Memory Cache > Reload Textures....
#XPression

There should be a flush HTTP cache option in the Tools menu. This should force it to re-download the next time the URL is requested.
