Curl Requests to Troubleshoot Cloudflare Invalid HTTP Headers

This is what we used to find a line break in the headers from Hyperikon via cURL. Make sure to use a ming client like Git Bash not Powershell or windows command line.

Use this to see what Cloudflare returns:

curl -sSL -D - www.hyperikon.com -o /dev/null

Use this to go around cloudflare, substitute your own domain & server IP:

curl -svo /dev/null --header "Host: hyperikon.com"
