SquidGuard: Target categories -> Expressions - are this RegExp or not ?

[Nachtfalke]

Hi,

I SquidGuard -> Target Categories I can enter expressions (word fragments).
I entered this expression:

.dlc|.ccf|.rsfd

But SquidGuard ignores the dot "." and filters URLs containing CCF.

Could someone help me how to block fragments containing a dot ?

/.*\.(dlc|ccf|rsfd)

@LEPM:

/.*\.(dlc|ccf|rsfd)

Ok, than in this case the description "Expression" means "Regular Expressions" ?
Then I think I know what I have to do ;-)

Thanks!
