Will changes to components flush the dispatcher cache?

Hi,

Let's pretend page P1 under /content includes a component C1 that is located under /apps/myapp/c1.

If I change C1, will the cached version of P1 be cleared from the dispatcher?

Today I noticed changes to a component I had written had not cleared the pages that were using that component from the dispatcher cache. I was wondering if this was only a temporary incident or if this is the expected behavior?

Thanks
