Replaceable Link Response

Starting from RedDog server v1.4.3, you can replace dynamically a value in links according what the user requested.

If needed, you have to add the value of {host} in “href” and “value” properties in links.

This feature are available to the next configurations:

Example

<tos>
   <notice>
      <title>Help Page</title>
      <description>
         <line>Here are a replaceable link to help</line>
      </description>
      <links>
         <link href="{host}/rdap-server/help">Link to help: {host}/rdap-server/help</link>
      </links>
   </notice>
   <notice>
      <title>Domain Requests</title>
      <description>
         <line>Link to Domain Requests</line>
      </description>
      <links>
         <link href="{host}/rdap-server/domain">Link to domain: {host}/rdap-server/domain</link>
      </links>
   </notice>
</tos>

For example, according to the diagram:

If you put 3 reverse proxies in front of your rdap-server with HTTPS and an user makes a request to https://rdap.registrar.foo/rdap-server/domain/test.foo

the response will be

{
	"rdapConformance" : ["rdap_level_0"],
     "notices" :
     [
       {
         "title" : "Help Page",
         "description" :
         [
           "Here are a replaceable link to help"
         ],
         "links" :
         [
           {
             "value" : "Link to help: https://rdap.registrar.foo/rdap-server/help",
             "href" : "https://rdap.registrar.foo/rdap-server/help"
           }
         ]
       },
       {
