Forward all http requests for http://test.abc.com/try to http://pass.xyz.com The idea here is to maintain the URL as http://test.abc.com/try on the user’s browser while the content/site served up is from http://pass.xyz.com. Please mail me on .

You can certainly rewrite the host header between LTM and the pool member, but are you trying to transparently send the user's info to whatever pass.xyz.com resolves to instead?

Can you please send me a iRule for this ? I will be highly thankful to you.

Something like this should work for you Dharmendra: when HTTP_REQUEST { if { [HTTP::header host] eq "test.abc.com" } { HTTP::header replace Host "pass.xyz.com" } } The users will still use the URL test.abc.com, their URL will stay the same and the data that is passed on to the servers will contain the new host header info.

Hi Naladar, its not working, my exact requirement is that if user type www.abc.com/aaa should redirect to www.xyz.com, latter is not in our network its some blogsite. Thanks

redirection but url not change on browser

Hi Nitaas, Thanks for your input. Following is the irule which irule editor is accepting,

elseif {[HTTP::host] eq "xyz.com" and [HTTP::uri] eq "/adblogtest" } {

HTTP::header replace location "http://www.google.com."

HTTP::uri "/"

HTTP::collect

NAME::lookup www.google.com}

}

It is not acception 'rule rewrite', it says command not valid in current context, pls suggest.

hi puneet,

the rule rewrite1 line is the rule name. i think u don't need to put it in irule editor.

in addition, why do u use HTTP::header replace location instead of host??

hth,

Hello All,

Requirement: My company URL shop.company.com need to redirect to the one external public URL suppose http://www.cisco.com/web/partners/index.html but user will only see shop.company.com. When I tried the Nitass iRule I am able to reach www.cisco.com but not getting through URI part. Could you please help me on the same.

you have to manipulate path of all the objects inside the page.

for example, in the cisco index.html may have several objects such as image, css. if they are using absolute path, no change is needed. anyway, if they are using relative path, you have to add /web/partners/ (because it is related to /web/partners/ not /).

hope this helps.

what did you get from troubleshooting e.g. log, tcpdump, etc?
