Build, test, and debug regular expressions
This regex matches file paths starting with "/asmproxy/" followed by alphanumeric characters, underscores, or slashes, ending with either a ".gif" or ".jpg" extension. Note that the dot before the extension is unescaped, meaning it will technically match any character before the image format. It is commonly used for extracting image URLs or paths in web scraping, log parsing, or content filtering.
