ace long referer uri

I have the problem with the ace loadbalancer that if a request with a long get uri and refer uri comes, i get a error page "the page can not be displayed". I get no error code, nothing back from the ace.

If i manipulate the refer uri to a short one => no problem. If a access the webserver directly => no problem with both requests.

Are there any restrictions with the length of the header from a request?

Re: ace long referer uri

yes there is a limit.

You can modify with an HTTP parameter-map.

switch/Admin# sho parameter-map HTTP-PARAM

Parameter-map : HTTP-PARAM

Type : http

server-side connection reuse : disabled

case-insensitive parsing : disabled

persistence-rebalance : enabled

header modify per-request : disabled

header-maxparse-length : 4096

content-maxparse-length : 4096

parse length-exceed action : drop

urlcookie-delimiters :


The following stats should increase when the length is exceeded.

switch/Admin# sho np 1 me-stats "-shttp -v" | i arse

Parse result LB msgs sent: 4 0

Parse result Inspect msgs sent: 3 0

Static parse errors: 0 0

Max parselen errors: 0 0
