ProxyPass v10/v11

@Hariharan_Padmanabhan:

If you are using this ProxyPass iRule, Please see Comment 5 in the instructions:

 5) ProxyPass does not rewrite links embedded within pages by default, just
 headers.  If you want to change this, edit the $static::RewriteResponsePayload variable in RULE_INIT
 and apply the default stream profile to the virtual server.
 Data Group Information
 For 10.0.x, you must define an external data group (type=String, read-only) which loads
 from a file on your BIG-IP.  For 10.1 and higher you can use an internal string data group with name=value pairings.
 The format of the file is as follows:
 "clientside" := "serverside",
 or
 "clientside" := "serverside poolname",
 The clientside and serverside fields must contain a URI (at least a "/") and
 may also contain a hostname.  Here are some examples:
 "/clientdir" := "/serverdir",
 "[www.host.com/clientdir"](//www.host.com/clientdir) := "internal.company.com/serverdir",
 "[www.host.com/"](//www.host.com/) := "internal.company.com/serverdir/",

If you are creating your own iRule, then you may want to start by reviewing the
