AltostratusURL Rewrite
we need to rewrite the incoming request to a different endpoint and add some additional parameters to the URL. The purpose of doing this is we don't want to expose the endpoint URL and the URL para...
Assuming all incoming url starts_with /rec/widgets, you can try below code
when HTTP_REQUEST { if { [string tolower [HTTP::uri]] starts_with "/rec/widgets" } { HTTP::header replace "Host" "sample.com" set new_uri "/api/v2/widgets[string range [HTTP::uri] 12 end]&account_id=5036&domain_key=example" log local0. "new_uri: $new_uri" HTTP::uri $new_uri return } }

AltostratusHey Sanjay,
Thanks for the quick reply!
Does the replacement host "sample.com" have to be in the same LTM? In our case, it's an external address.

It can be hosted any where. You would need to modify the iRule above to create a pool for "sample.com" and use it with pool command before return statement.
Make sure pool is reachable from the LTM.

Sure! I'll do that. Thank you!
I have one more query - What if the account ID keeps changing depends on the user (&account_id=5036), is there a way to make it dynamic?
- spalande
In your explanation, I don't see accountID is coming in incoming URL
https://example.com/rec/widgets/item/McBq3g?=,&_br_uid_2=uid=59512300:v
from where are you retriving this account ID? I thought it's static URI you are appending with a rewrite. Did you miss anything?
- MohanK
Yes, You're right. I was wrong, sorry about that :)
We are testing the iRule, this weekend. I'll keep you posted.
Thank You so much for all your help!
