Odd web site behaviour using any browser in FC2 and FC3

[Greg Guldenschuh]

Rahul,
   Although the specific reference supplied was not the issue, you pointed 
me close enough to the answer that I found it.  The article you mentioned 
showed how to set one of thewin_scaling parameters.  While looking around in 
/proc/sys/net/ipv4 I found a file named tcp_ecn which contained the value 
"1" I changed it to "0" using the echo command in the article and that fixed 
the problem I was having with the site www.galottery.com.

Thanks for the assist!
Greg Guldenschuh
