Check last-modified date


Gives an error for any page that has not been modified within a specified time frame. DeepTrawl takes the last modified date from the HTTP header, or local file system, for Internet and local pages respectively.


Note: Not all servers send a last-modified header. By default DeepTrawl will warn you for any page which doesn't return one. This warning can be turned off (see configuration below).
