[MarkLogic Dev General] xdmp:http-post and xdmp:http-get proxy

[Dinesh]

Hello,

 

Could you please advise how to use xdmp:http-post and xdmp:http-get for
proxy? The MarkLogic Server running behind a proxy and trying to use
xdmp:http-post and xdmp:http-get functions to connect the external site, but
getting <code>400</code> <message>Bad Request</message>.

 

Will MarkLogic Server 7.x support proxy options?

 

 

1.       Request and Response without proxy.

                                                

Request

let $uri := "https://www.google.com.sg/?gws_rd=ssl#q=xml";

let $result := xdmp:http-get($uri,

                                <options xmlns="xdmp:document-get">

                                                <format>binary</format>

                                </options>)

  return $result

2.       Request made as discussed at this
http://markmail.org/message/sbfj44jtmpsyopyh   (with proxy server)  

 

Request

let $proxy := "http://172.21.10.60:3128"; (: simple http proxy :)

let $uri := " https://www.google.com.sg/?gws_rd=ssl#q=xml";(: target web
service :)

 

let $host := tokenize($uri,'/')[3] 

let $proxyuri := concat($proxy, '/', tokenize($uri, '/')[last()])  

 

return xdmp:http-post(

      $proxyuri,

      <options xmlns="xdmp:http">

        <headers>

          <Host>{$host}</Host>          

        </headers>

      </options>

    )

Look at the URL formed by the above request

 

<div id="content">

<p>The following error was encountered while trying to retrieve the URL: <a
href="/?gws_rd=ssl#q=xml">/?gws_rd=ssl#q=xml</a></p>

 

Thanks.
