Re: Reverse proxy - retry connection in response to error 50x

From access.log:

10.1.21.114 - - [21/Oct/2014:14:01:55 -0700] "GET /xxxxx_prod/u2/cfs056.ashx?clearScreenInputs=UserID=QCFJB|GoFlag1=Y|GoFlag2=Y|GoFlag3=Y|GoFlag4=Y|GoFlag5=Y|Parm0=Y|Parm1=Y HTTP/1.1" 302 168 "https://xxxxx2.nv.gov/xxxxx_prod/u2/landing.aspx" "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0)"

The last entry shows the 500 that I would like to handle with a retry.

There's no corresponding entry in error.log
