Broken Link Checker
Broken Link Checker scans links on the active webpage and checks whether they are broken or redirected.
About Broken Link Checker
Broken Link Checker scans links on the active webpage and sorts them into valid or broken categories based on response code, including internal and external redirects. It can be used in a popup window or embedded as a frame in the page, with an Inspect button that brings a checked link into view and highlights it.
It checks up to five links at a time with a 10-second timeout per link; timed-out links receive a 504 code and are listed as broken. Optional modes include links from sub-frames and from blank frames, but running the tool on multiple pages at once is not recommended.
