Custom HTTP Header

Custom HTTP Header

Last Updated: May 13, 2013 03:28PM CDT

One example of how a custom header produced by Asset Manager may be useful is if the application is going to be embedded in another 3rd party application using something like HTML <iframe> tags.  Since RF Code won't use cookies by default, a custom header will be necessary to add a policy, such as a Compact P3P, to allow the browser to leverage/use the cookies.  To do this, the "jetty.xml" file will need to be edited on the Asset Manager.  By default, this file is located in the "C:\Program Files\RF Code\Asset Manager\jetty\etc" directory.

Near the end of the file, in the final "<Set name="handler">" section, you'll need to add a custom <item> after the last item. 

Here's what the end of the file looks like before the edit:
 

<Set name="handler">
   <New class="org.mortbay.jetty.handler.rewrite.RewriteHandler" id="Rewrite">
     <Set name="handler"><Ref id="oldhandler"/></Set>
     <Set name="rewriteRequestURI">true</Set>
     <Set name="rewritePathInfo">false</Set>
     <Set name="originalPathAttribute">requestedPath</Set>
     <Set name="rules">
       <Array type="org.mortbay.jetty.handler.rewrite.Rule">
             <!-- add a rewrite rule -->
         <Item>
           <New class="org.mortbay.jetty.handler.rewrite.RewritePatternRule" id="">
             <Set name="pattern">/cgi-bin/nph-nbRmtLinkCGI</Set>
             <Set name="replacement">/rfcode_zonemgr/cgi-bin/nph-nbRmtLinkCGI</Set>
           </New>
         </Item>
       </Array>
     </Set>
    </New>
 </Set>
</Configure>

Here's what it would look like after the edit:
 

<Set name="handler">
   <New class="org.mortbay.jetty.handler.rewrite.RewriteHandler" id="Rewrite">
     <Set name="handler"><Ref id="oldhandler"/></Set>
     <Set name="rewriteRequestURI">true</Set>
     <Set name="rewritePathInfo">false</Set>
     <Set name="originalPathAttribute">requestedPath</Set>
     <Set name="rules">
       <Array type="org.mortbay.jetty.handler.rewrite.Rule">
             <!-- add a rewrite rule -->
         <Item>
           <New class="org.mortbay.jetty.handler.rewrite.RewritePatternRule" id="">
             <Set name="pattern">/cgi-bin/nph-nbRmtLinkCGI</Set>
             <Set name="replacement">/rfcode_zonemgr/cgi-bin/nph-nbRmtLinkCGI</Set>
           </New>
         </Item>
         <Item>
           <New id="" class="org.mortbay.jetty.handler.rewrite.HeaderPatternRule">
             <Set name="pattern">*</Set>
             <Set name="name">CUSTOM_HEADER</Set>
             <Set name="value">Value of the header</Set>
           </New>
         </Item>
       </Array>
     </Set>
    </New>
 </Set>
</Configure>

The name and value are arbitrary and can be changed to suit your needs.  Once this change is made, the Asset Manager service will need to be restarted.
