hi,

in my virtual server, i added pool used fqdn 3 server for example test1.com,test2.com and test3.com on the one pool 

When i hit access to the virtual server i got error bad hostname but i try to hit on the pool is not error

I added rewrite url translation type request client http://192.168.229.120:9000/ and server http://test1.com that is i can access to the server.

I added in the same rewrite client url is same but different server url got error must uniq on the client. 

How to resolved this issue or another solutions,

Should fqdn as pool member must used rewrite or no?

thanks

Hello,

from what i understand is, you have configured the pool members with the FQDN instead of the IPs, so F5 will try resolving their names to get their IPs, am i right?

https://support.f5.com/csp/article/K16545

so how do you access the virtual server? as the bad hostname error appears when the source is not able to resolve the fqdn. If each of the pool members is having different FQDN for the service, try using one of the pool members only and test the rewrite url again.
