Dear HomeAway customer support:

When I visit

https://www.homeaway.com/owners/index.cfm?fuseaction=availability&pro_id=3020695

and click the [Google Calendar] link at the bottom of the screen, I am offered this link to cut-n-paste:

https://connect.homeaway.com/icalendar/hacalendar.htm?cid=89d5c6d06a2649c1978a09d450235777

When I use Google Calendar, click the [Add] link, and paste in the above URL, I receive the error:

Could not fetch the url because robots.txt prevents us from crawling the url.

This is due to the following text in http://connect.homeaway.com/robots.txt :

User-agent: *
#Disallow: /search/refined/

User-agent: wegobot
Disallow: /

Google is interpreting this as:

User-agent: *
User-agent: wegobot
Disallow: /

Which Google thinks means DON'T INDEX YOUR SITE AT ALL!!!!!

The fix is to either remove

User-agent: *
#Disallow: /search/refined/

or move it to the end of the file, where it will not be mis-interpreted.

How about giving me an extra year for taking the time to diagnose, and inform you of this SERIOUS issue with Google, the most used search portal on the internet!!!
