Double pointer reference

I'm wondering when inserting large link list, is there a way to point to the right page rather than searching for it everytime.
What i mean is i insert a webpage into a list and create another list under it. the problem is for every new url inside that website i have to search for the webpage all the time.

I think is there a way to do this with double pointers such as

insertpage(char *name, webpage **page)

insertURL(char *urlname, webpage *page);

so when a new page is create, the *page will be already pointing to the right page.

im finding it hard to find some good examples on double pointers.
