server validation regular expression case insensitive?

Hello Ray,
I have a problem trying to understand how server validation with regular expression work.
I need to validate a text form field against a string composed by at least 3 words.
I just created a regex and it works online on some regexp online tools.
Here it is:

/^(la)?\s*chiesa\s*di\s*gressoney\s*$/

It works but it's case sensitive.
How can I change to case insensitive?

These are the strings it should match:

la chiesta di gressoney
La chiesa di Gressoney
LA CHIESA DI GRESSONEY
Chiesa di Gressoney
Chiesa di gressoney

... and other mispelled cases...
Can You help me?
TIA
tony

Where are you adding the regular expression? Is this client or server validation?

I'm using server side validation.
Ciao ;)

I came up with this regular expression:

([Ll][Aa])?\s*[Cc][Hh][Ii][Ee][Ss][Aa]\s*([Dd][Ii])?\s*[Gg][Rr][Ee][Ss]{2}[Oo][Nn][Ee][Yy]\s*

I's a bit inelegant, but it seems to work.
Is there a better method?
TIA

For server validation just add 'i' at the end to make it case insensitive like:

/^(la)?\s*chiesa\s*di\s*gressoney\s*$/i

Thanks Ray,
what about client side validation?
does this code work the same way?
TIA

It depends on the validation. Our jquery validation works the same way, but other client validations might have their own method.
