Rewrite URLs to include the session ID.
What it does:
- rewrites the URLs outputted to have the session ID, if the user
is not accepting cookies and is using a standard web browser.
- handles rewriting URLs for the queryless URLs option.
- can be turned off entirely by setting $scripturl to an empty
string, ''. (it wouldn't work well like that anyway.)
- because of bugs in certain builds of PHP, does not function in
versions lower than 4.3.0 - please upgrade if this hurts you.
