Stop Caching Images in an email!
Posted on 2006-06-05
I have an existing system of "Support Requests", where members in the computer department are all sent an email when a user needs help. I'd like to create it so in Outlook, when the view the support request email, they will get a visual image cue as to whether the request is "Unassigned", "Pending fix...", or "Resolved".
Functionally, I can do this no problem, as I'm a web programmer, so changing the image on the other end based on the URL is no problem. However, Outlook isn't working with me, as it saves the first image brought to the clients computer, and it won't ever "refresh" it. So even though the request has gone through all the steps, Outlook is still showing the first picture it ever downloaded.
I've tried doing some HTTP tricks to get outlook not to cache the image, but it doesn't appear Outlook listens to these. Does anyone here have any ideas about how I can configure this email/image so Outlook doesn't cache images? Preferably, I'd like to do this in the email, so I don't have to touch everyone's PC.
