iRule to redirect a variable to http

I have to use HTTP_referrer in it..........., i would like to have as http_referrer (which is used for that : http://en.wikipedia.org/wiki/HTTP_referer) wth the original DNS calledi replied in another discussion.

Can this maintain persistent session? Any traffic that goes into this iRule should have persistent session on the cache servers.

 

What can we put in?it seems your post is not complete. anyway, what persistence method do you want?

 

 

is carp applicable?

Nitass,

 

 

thanks! for the 2nd query, here's the setup:

 

 

SETUP:

 

1.Inbound and outbound traffic falls on the same VLAN. Using same interface.

 

2.INBOUND: From internet to firewall to F5

 

3.OUTBOUND: F5 to Cache servers

 

4.Inbound VS is configured with 2 members ( Cache 1 and Cache 2)

 

5.Used iRule to rewrite URL

 

6. Servers are on the same VLAN as the self-ip. (only one interface active for F5)

 

 

OPERATION:

 

1.Client initiates HTTP request with URL: www.google.com.acme.com.nz

 

2.URL goes to public FW IP, this get NATed then goes to the F5 box

 

3.With iRule, acme.com.nz gets truncated, then returns back www.google.com to the client browser.

 

4.This is working, and F5 rewrites it.

 

 

Queries:

 

What happens to the succeeding traffic upon rewrite?

 

Does it go direct to the pool members?

 

Do we need persistence on this, to make it force to go the succeeding traffic?

 

How can we put succeeding traffic will always go to f5 for it to be cached?

 

or will just be an iRule telling the traffic to go to pool members?

 

 

Sorry for the lot of queries.

 

 

I tried it on my browser. It seems like after the first hit, user gets the rewritten URL, then goes back to the normal traffic, bypassing F5.

 

 

 

thanks!

 

Nitass hi,

 

 

In simple terms, F5 needs to pass the request to proxy ( cache servers) upon rewriting the URL.

 

 

user-->F5[rewrites URL] & [forward request] --> Proxy (Cache) / Cache acts as proxy, then respond to user.

 

 

i put question in your new post below.

 

 

iRule rewrite then forward request to pool
