help with http::path

Hello i am trying to add logic in to account for different branches of testing in my irule.

 

currently we adjust the http:path to a particular value

 

set apiPathStage "apiproxy/apiproxy.aspx"

 

 

HTTP::path $apiPathStage

 

example request may be http://1.2.3.4/interface.asp?Command=testcommand

 

converts to http://1.2.3.4/apiproxy/apiproxy.aspx?command=testcommand

 

this works great.

 

going forward the developers want to be able to add in additional branches to the path such as:

 

http://1.2.3.4/test/interface.asp?Command=testcommand

 

http://1.2.3.4/stage/interface.asp?Command=testcommand

 

http://1.2.3.4/dev/interface.asp?Command=testcommand

 

I am looking for a way to take the first part of the entered path and insert it before the applied path value.

 

so that the 3 examples above would generate:

 

http://1.2.3.4/test/apiproxy/apiproxy.aspx?command=testcommand

 

http://1.2.3.4/stage/apiproxy/apiproxy.aspx?command=testcommand

 

http://1.2.3.4/dev/apiproxy/apiproxy.aspx?command=testcommand

 

any help would be appreciated.

 

thanks,

 

Ben
