Layer 7 loadbalance for HTML content

JEFFREY MONACO — Thu, 26 Jan 2012 20:48:04 GMT

We're trying to understand how "match http content ...." works.

We're trying to match this:

http://www.acme.com/widgets/stories.aspx?section=prodlist1&promo=special

We've coded this:

class-map type http loadbalance match-all redirect_to_prod_site

10 match http header Host header-value "www.acme.com"

20 match http url /widgets/stories\.aspx

30 match http content "section=prodlist"

It matches if we remove 30 match http content "section=prodlist"

I think the issue relates to what is meant by "content". We've been referring to this document:

http://www.cisco.com/en/US/docs/app_ntwk_services/data_center_app_services/ace_appliances/vA3_1_0/configuration/slb/guide/classlb.html#wp1206722

The manual says this, "The ACE performs regular expression matching against the received HTTP message body from a particular connection based on a regular expression string in the message body (not the header)."

We know that "match http url" stops at the "?". Isn't the body the part that comes after the "?"?

Hi Jeffrey,

The part after the "?" is still part of the HTTP header, not the content. On ACE, this part is named "secondary cookie"

To match on it, you can use the statement "match http cookie secondary section cookie-value prodlist1"

I hope this helps

Daniel
