💡 Hint

Common Mistakes

Omitting the caret ^ causes matching anywhere in the string.

Missing the leading slash in the pattern.

The caret ^ anchors the regex to the start of the string. To match URLs starting with '/images/', use ^/images/.

4fill in blank

hard

Fill both blanks to match URLs ending with .css or .js using a case-insensitive regex.

Nginx

Drag options to blanks, or click blank then click option'

A\.(css|js)$

B\.(jpg|png)$

C.css$

D.js$

💡 Hint

Common Mistakes

Using separate patterns for .css and .js instead of combined.

Not escaping the dot.

The regex \.(css|js)$ matches strings ending with '.css' or '.js'. Using ~* makes it case-insensitive.

5fill in blank

hard

Fill all three blanks to match URLs starting with /api/ followed by digits, case-sensitive.

Nginx

location ~ [1][2][3] { }

Drag options to blanks, or click blank then click option'

A^/api/

B\d+

C$

D[a-z]+

Attempts:

3 left

💡 Hint

Common Mistakes

Omitting anchors causes partial matches.

Using wrong character classes for digits.

The regex ^/api/\d+$ matches URLs starting with '/api/' followed by one or more digits until the end of the string.
