regex - matching a string with the first occurrence case insensitive

Question

I need to modify a regular expression that matches a url for a redirect. The main part of it is this:

#^/webpages/ProdPage.aspx|^/default.asp#

That (i think) matches all the occurence that comes from webpages/ProdPage.aspx or default.asp . I need to modify it so that it will match default.asp or Default.asp . Maybe I should just add an i after the delimiter but I don't want the entire expression to be case insensitive.

thanx Luke

Answer 1

Change your default.asp to [dD]efault.asp to allow just the d to be lower or upper case.

Additionally, you might consider changing your . to \\. as you want it to match a literal dot (ProdPage.aspx, default.asp). Otherwise, . will be interpreted in its regex sense meaning "any character except newline", so a page webpages/ProdPageaaspx would match (even though it's extremely unlikely...)
