Hello,

I am wondering if something like this is possible. I have some legacy urls coming from Google searches that need redirection. For example:

/portal/group/auditor/page/default -> /departments/auditor
/portal/group/treasurer/page/abc -> /departments/auditor
/portal/media-type/html/group/sheriff -> /departments/auditor
/portal/media-type/html/user/anon -> /departments/auditor

Tuckey URL rewrites is not an option to me. 

I would settle for a redirect to "/departments" if what I'm trying to achieve is not possible. I tried  Vanity URL like shown below but it's not working for me:

Uri: /portal/media-type/html/([A-Za-z0-9]+)
Forward To: /departments

Many thanks in advance for any hints.

One trick I use is hunting things down in the 404 page:
#set ($thispage=$request.getAttribute("javax.servlet.forward.request_uri"))
#if ($thispage.contains('/catalog'))
<meta http-equiv="Refresh" content="0; url=http://marywood.smartcatalogiq.com/" />
## alternatively you can: $response.sendRedirect($nrepath)
#end


I think you could also, in this case, make a structure of redirects and use the URLMap feature to match.
From your example, are you redirecting each and every one to the same place? I'd use the idea above.
But if each of those other links is supposed to map to a different place, you could absolutely use URL map and a structure to maname many calculated redirects.

I think Apache or Nginx redirects would be ideal if you have access to them.


Probably not as easy if you are cloud hosted.

Also, be careful as '/portal' is a protected folder path in the dotCMS system.
If you did a broad redirect, you might break your access to the backend. By situating it as part of the 404 - it only triggers as a last resort.

Thanks, this is a good advice. I currently have vanity url with uri "/portal/(?s).*/(?s).*" in place. So far, nothing is seems broken on the back end but I see your point. I will try your 404 page trick.

Mark, 

The strange problem that I'm having with the statement below is that sometimes it returns a random url (not the same url that sent the user to the 404 page). Almost as if it was getting attribute from another session.
 
#set($badurl = $request.getAttribute("javax.servlet.forward.request_uri"))

Other than that, the solution would work perfectly:

#set($badurl = $request.getAttribute("javax.servlet.forward.request_uri"))
## Sample legacy url: portal/group/clerk OR /portal/media-type/html/auditor/page/default
#if($badurl.indexOf("/group/") >= 0) 
    #set($path_array = $badurl.split('/'))
    #foreach($p in $path_array)
        #if($p == "group")
            #set($groupName = $path_array.get($velocityCount))
            ## Prevent infinite loop if the department does not exist
            #foreach($con in $dotcontent.pull("+contentType:Department +Department.legacyGroupName_dotraw:$groupName +deleted:false +working:true",1,"score,modDate desc"))
                <meta http-equiv="Refresh" content="0; url=$host/departments/$groupName/"/>
            #end
        #end
    #end
#end

Interesting. Good code.
Perhaps check the 404 page properties and turn off caching? dotCMS defaults to caching for 15 minutes which is absolutely not what you want to do here!

Hi Mark,

Your suggestion worked great! I've added "?dotcache=no" to my Forward To address on all the vanity URLs and so far the solution is 100% effective. Thanks again.

Yeah, the default cache-15 can be terrible if you are trying anything clever on your pages. A 404 page should *always* have some sort of custom reply built in based off of what was searched for. You can always use the manual cache on the page if you are really concerned.

Thanks again for the tip. Things are getting more clearer every day.
