If we have a URL :
https://www.example.com/123.html
I wish to check if other web pages are present by changing certain portion of URL , in this case we can do by changing numbers.
Hence :
https://www.example.com/124.html
So how can i do it , say run a script , which checks presence of web pages in this directory by changing , in this case , last three numbers , say from 000 to 999 ?
