Part of the beauty of twisted is that you don't actually need to do anything special to achieve that, just create a global dict or other object of your choice and access it as needed. More likely what you need to look for is a cache expiration mechanism, I've linked in lrucache (<a href="http://pypi.python.org/pypi/lrucache/0.2">http://pypi.python.org/pypi/lrucache/0.2</a>) in one case, but usually I just write my own constraints as appropriate. <br>
<br>It's often misunderstood, but in twisted you are writing an actual server rather than just some methods for servicing requests. The server will run until stopped and all global or even local variables will remain in memory unless deleted or dereferenced and garbage collected. Rather than doing something special to get a persistent variable you need to do something special when you want a non-persistent one. <br>

Caching the results of some particular method calls, so other server<br>
side methods can access those results (I'm thinking about example of<br>
global variable per entire server, so once imported, such variable<br>
content could be access).<br>
