I want to put below condition on irule, please help 1. If source IP matches and URI is /A and /B traffic should be forwarded to POOL A 2. If user is accessing /C-new, rewrite URI to /C and forward...
Hi Bhupendra ,
in Step 2 of rewrite >>> do you need the source ip matches as well or Not ?
So you need to match on specific source IP address/address first and then match /A or /B then move traffic to pool A but if the same match on source ip address/addresses but with uri starts with /c-new modify it to be /C and forward traffic to pool A
if non of those forward to pool B
that's Correct ?Maybe think about using a local traffic policy rather than an iRule. It will be more efficient and easier for you to manage
Hi Bhupendra ,
As PeteWhite recommended , yes it's eaiser than iRule and will give you the same result.
it should be like this :>>> Note that , the last condition "3rd match " should be All Traffic and then do those Actions ( Log and Forward to default pool )
This is an overview about Local Traffic policy :

Goodluck

So you need to match on specific source IP address/address first and then match /A or /B then move traffic to pool A but if the same match on source ip address/addresses but with uri starts with /c-new modify it to be /C and forward traffic to pool A
if non of those forward to pool B
that's Correct ? ----------------->>First condition match on specific source IP address/address first then match URI /A or /B for selected source IPs then move traffic to pool A
Second condition -any source with uri starts with /c-new modify it to be /C and forward traffic to pool A
If no condition match from 1&2 then default traffic should be route POOL B

GoodluckHi Bhupendra ,
Use this irule :when HTTP_REQUEST { if { ( [IP::addr [IP::client_addr] equals x.x.x.x ] ) and ( ([HTTP::uri] starts_with "/A") or ([HTTP::uri] starts_with "/B" ) ) }{ log local0. " First Condition matched >>>> GO TO POOL A 🙂 " pool POOL_A } elseif { ( [HTTP::uri] starts_with "/C-new" ) }{ HTTP::uri [string map -nocase {"/C-new " "/C"} [HTTP::uri]] log local0. " 2nd Condition matched (String MAP did it work ) >>>> GO TO POOL A 🙂 " pool POOL_A } else { log local0. " 3rd Condition matched ( Default path ) >>>> GO TO POOL B 🙂 " return } }Don't forget to assign POOL_B as a default pool in Virtual server resources , to forward traffic in case the last condition ( Default ) triggered.
>> Also Make sure that there are no multiple requests are sent for each web page.
I mean :
if you sent req like this http://10.10.10.10/A by the specified source address it should be forwarded correct to pool_A.
But what if at the same time your web page needs multiple requests like http://10.10.10.10/image.phpso make sure you send only single request per page.
GoodluckHi Bhupendra ,
Have you tested the irule as well ?
just test it , you may take it as a reference in further implementations.
Also it will add to me that my code was correct or need further modifications.

That's correct
