so, rule to be in one line but to have two option to acees url like:

/foo-bar-2-steps/

/foo-bar-2-steps-eq/

Answer 1

One of the following:

• Use two rewrite rules, one for each case
• Put a question mark after the optional part, like this:

foo-bar-([a-z]+)(-([a-z]+))?

Here, the second parameter is optional. Note that this changes your numerical indexes, since you use extra parenthesis.
