how i can configure the Proxypass in BIG LTM f5(Pool virtual server,Proxy and monitor)

Take a look at this, https://devcentral.f5.com/wiki/iRules.ProxyPassV10.ashx. It may be what you're looking for. A more specific question may help get a better answer.

You can also take a look into the rewrite profile option, uri translation. There are some gotchas to look out for, but is you can give a little clearer info on what you want to do, I might be able to help.

The rewrite profile is supposed to give better performance over an iRule.

I am plan do it on v11,

I’m going to access http://ecmdev.network.dev/ecmtestdev/llisapi.dll?func=ll&objId=64554229&objAction=browse&viewType=1

I’m expecting the LTM to redirect to the http://outagemessage-dev.network.dev/ and I’d like to include everything after the ? in the original request url.

For instance

http://ecmdev.network.dev/ecmtestdev/llisapi.dll?func=ll&objId=64554229&objAction=browse&viewType=1

should redirect to

http://outagemessage-dev.network.dev?func=ll&objId=64554229&objAction=browse&viewType=1

I need irule for this
