I need to extend the default AsyncPostBackTimeout property for the AJAX Scriptmanager because I am forever getting timeout error messages appearing when creating child portals (I have somewhere in the region of 200 child portals!).

The timeout occurs during the ClearHostCache process.

To do this I have had to amend the core code - I have chosen to add this property in the Library\components\Skin\Skin.vb file just after it adds the EnablePartialRendering property.

I REALLY don't like this for two reasons:

1. I am not sure this is the correct place to do it?
2. I really don't want to be amending the Core Code as these changes are bound to get lost in a future upgrade

SO, is there a better place to do this?

If so, can someone please tell me where to do it and more importantly HOW to do it?

With the new versions of DNN (v5 ->) can this timeout property now be changed without having to amend core code?

I also want to extend the DB timeout length via the web.config file to try and cater for the issue I have with timeouts occurring during the creation of child portals (see this thread for more details - www.dotnetnuke.com/Community/Forums/tabid/795/forumid/118/threadid/291930/scope/posts/Default.aspx)

Would doing this have any damaging affect to the rest of my site?

Any good reason NOT to change the timeout durations?

Any advice would be most gratefully received!
