[spook-l] Refreshing JPEG snapshots

[Vladimir Lasky]

G'day Nathan,

It appears that Mozilla/Firefox has a bug or limitation that causes the browser to cache JPEG snapshots unconditionally, i.e. they ignore that HTTP header that you added a while ago to prevent caching. This means that when you reload an image using a Javascript event handler, nothing changes.

The only way to fix this quickly, is to use the old trick with Javascript and the query string. e.g.

"http://server/stream1.jpg?" + new Date().getTime();

So this would mean modifying spook to ignore everything in the URL starting from the question mark. What are your thoughts?

Regards, Vlad.
