Mongrel users - Apr 2008 - Error log, when using apache2.2.x modproxy with mongrel

Hi all
im new to use mongrel, my mongrel version is 1.1.4
and apache is 2.2.8

when i using apapche+mod_proxy+mongrel,
there are some error in my log file and make apache 502  prxoy error.
ex:
proxy: error reading status line from remote server localhost
proxy: Error reading from remote server returned by /test/show
But it works well if i access mongrel directly.

and the mongrel.log will have error like below:
then i try to put the REQUEST DATA into test_http11.rb, looks like
"Connection:
Keep-Alive\r\nGET /test/show HTTP/1.1\r\n " makes it confuse.
