Probing

Validates a list of urls, checks to see if they are alive or not.

httpX

# https://github.com/projectdiscovery/httpx
# go install -v github.com/projectdiscovery/httpx/cmd/httpx@latest
cat urls | httpx -random-agent -retries 2 -o out

Hold down!

For some reason httpx fails to retrieve all good working urls. It is recommended to run httpx more than once to achieve better results.
