Q:

Ruby http, net/http, httpclient: can't parse www.victoriassecret.com

I am using httpclient gem, it works fine on Windows, just moved to AWS EC2, tried it on https://victoriassecret.com and it gets this response:
= Response

HTTP/1.1 920 Unknown
Content-Type: text/html

It does not work only with this website, httpclient get https://google.com for example works fine.  But on Windows I get normal response from httpclient get https://www.victoriassecret.com.  Butt when using standard NET/HTTP library I get the same 920 response on Windows. 

A:

This isn't ec2 related.  It's most likely related to the User Agent header sent by the various http library implementations.  
For example, they clearly don't like 'wget':  
curl -A "Wget/1.13.4 (linux-gnu)"  -v https://www.victoriassecret.com
