My IIS7 URL rewrite rules keep disappearing

Question

I have regular IIS7 rewrite rules -- the SEO ones (canonical name tags, trailing slashes, lowercase letters). They work fine.

But then a day later, or even a few hours later, they're gone -- as if they were never there in the first place, so I have to redo them again in IIS7.

Can anybody tell me why this is happening, and what I should do? Thanks!

Check that there isn't something else that's updating your web.config file.

Accidentally redeploying over it can cause this to happen since IIS stores the rewrite rules in your web.config file.
