Partial content problem with facebook

Wed Feb 23 22:37:47 CET 2011

Thanks for the quick answer i gonna try to explain it in a better way.

In the page im hosting exist a button to share the page on facebook, 
this button call a facebook php: http://www.facebook.com/sharer.php? 
with the URL of the page you want to share as a argument, then facebook 
calls my webserver page and insert an "article" on the visitor fb page, 
but when we try to do this trough varnish its return 206 partial 
content, it happened before with 2.1.3 on other host and it was fix 
editing include/http_headers.h and recompiling but for this host in 
particular that doesn't work, neither upgrading to 2.1.5.
