Magento: Change Config option without saving it

Question

In my Magento module, I want to change a config option for just one run - the change should not be saved in the database.

It is only to change it with certain conditions during runtime, so that all subsequent core calls etc use that option.

I know you can use something like Mage::getConfig()->saveConfig(...), but that actually saves the change in the database.
I'm using Magento 1.5.

Is that in any way possible?

Can't you do it simple ? get the old value, change it, run your script, save the old value — dagfr

@dagfr No because I have to set it very early (right at App::run) and it has to span over all of magento's functionality. — Lanbo

You can also register the value you need (with Mage::register) and use this registry instead of the config everywhere you need it — dagfr

@dagfr Which would imply I have to re-write half of Magento's core libraries. The value I need to change is the {{base_url}}. — Lanbo

Ok, and what is the purpose of changing this value ? What are you trying to do ? — dagfr

Try to this:

Mage::getConfig()->setNode($path, $value);

Use $store->setConfig('config_path', 'value_to_set') to take in memory cache into account. Note that this is independent from the Magento config cache, but if you call Mage::getStoreConfig() twice with the same path it won't read the loaded XML structure but instead look it up in an array.
