my test, is error 426

Hi folks,
Okay I managed to test at the location I encountered yesterday.
As I shared,  my search suggested that this is an HTTP protocol related 
error.
My test indicates that indeed this is the issue.
When you get the 426 error,  you are also provided with the solution, what 
protocol the server will accept.
When I used the option menu to change from HTTP 1.0 to HTTP 1.1 the site 
link worked just fine.
Those of you using adaptive tools, if your specific tool allows for 
review, check the information provided  just before the 426 line itself.
Hope this helps others,
Karen
