How to Filter CSS, JS, Images and Other Static Files in Fiddler
This short guide shows a regular‑expression rule for Fiddler that blocks common static resources such as CSS, JavaScript, images, icons and audio files, and provides a link to a Chinese‑language Fiddler localization package.
Fiddler rule for filtering static files
Defines a regular expression that matches any HTTP request whose path ends with one of the extensions css, ico, jpg, png, gif, bmp, wav, js, or jpeg. The expression also accepts an optional query string after the extension.
REGEX:(?insx)/[^\?\/]*\.(css|ico|jpg|png|gif|bmp|wav|js|jpeg)(\?.*)?$The flag group (?insx) sets the regex to be case‑insensitive ( i), to let . match newlines ( s), to ignore whitespace and comments ( x), and to treat the pattern as a single line ( n). Adding this rule to Fiddler’s filter configuration causes the tool to ignore (hide) those static‑resource requests during capture.
