Regular Expression that matches any .aspx url

Question

The text I was going through mentioned that following regular Expression matches any .aspx url:

@"?i:^.*\.aspx.*$"

I couldnot understand what ?i:^ did while matching. Pls. explain what part it matches in urls like http://localhost:2447/Out.aspx, https://msdn.microsoft.com/en-us/library/88c54tsw.aspx.

Please dont use text-speak, there are many people from all around the world and it may be difficult for some to understand. — Lima, Nov 07 '15 at 15:33
best regex for checking file extension is "\b\w+\.(?=aspx)\w+\b" in your case — Sebastian 506563, Nov 07 '15 at 20:47

?i means ignore case. Your pattern also has some unneeded fillers. If you only want to check if the string contains .aspx, use this:

(?i)\.aspx

// Match:
http://localhost:2447/Out.aspx
http://localhost:2447/Out.AsPx/suburl
