ACE 4710 Redirection based on incoming Spanish Language

[Stanley Fry]

I have a customer that wants to redirect incoming traffic to a different url or host based on the end users language. Spanish in particular. What is the best way to accomplish this task with the least amount of issues.

You will need to check if the http request contains a heade specifying the user is using spanish.

Seems like the only way.

You can use an http class-map to match traffic that has the spanish header value.

Can I find any sample code anywhere? I have never had to do this before

for a different language.

If you capture a sniffer trace of any HTTP traffic, you will see that every request contains a line like this :

"Accept-Language: de"

So, in this example the request contains information that the browser accept German (DE).

If you sniff a request from a spanish browser, you should see a similar line with the "SP" letters.

Then with ACE, you can match those requests with a class-map like below :

AceC6k2/Admin(config)# class-map type http load Spanish
AceC6k2/Admin(config-cmap-http-lb)# match http heade Accept-Language header-value sp
AceC6k2/Admin(config-cmap-http-lb)#

Then inside your policy-map you can use this class-map to differentiate spanish request from the others.

policy-map type

AceC6k2/Admin(config)# policy-map type loadbalance http first-match Web
AceC6k2/Admin(config-pmap-lb)#

AceC6k2/Admin(config-pmap-lb)# class-map Spanish

<.....do something here for spanish browsers .....>

AceC6k2/Admin(config-pmap-lb)# class class-default

<..... do something here for the other browsers ......>
