Description

Conforms to various RFC specifications

Captures key components of url:

  • Protocol
  • Authority
  • Port
  • Path
  • Query
  • Fragment

Also because this is specifically looking for an image file, captures full file name & extension (jpeg/jpg/gif/png)

Limitations to this regex:

  • Only http or https protocols are allowed
  • Only named hosts can be used, not IP addresses
  • Does not support unicode
  • Does not support escaped characters

The path & filename detection is still a little "free" in standard URI style - they allow a wide range of characters
