Dispatcher configuration with virtualhost issue on port appending

[VikramP8]

Hi,

I'm trying to setup a new publish instance in aws linux machine. I have setup the aem publish environment and trying to access via the hostname.

So the Request flow is Dispatcher server -> ALB (Protocol port: 7000) -> AEM Publisher Server (App Instance running on 7000)

I have setup all the dispatcher configurations and routing the traffic through renders to the ALB on port 7000

When i access the host url lets say aempublish.com it's going to aempublish.com:7000/content/we-retail.html where the page is not loading. If i manually remove the port and hit url the page loads fine. I have setup the proxy and rewrite rules as well but still facing the same issue.

Checking the network the request is getting redirected twice with 302 status code

1) aempublish.com -> aempublish.com/index.html

2) aempublish.com/index.html -> aempublish.com:7000/content/we-retail.html

Dispatcher.any 

    /virtualhosts
      {"aempublish.com"}
    /renders
      {
      /rend01
        {
        /hostname "internal-uai100567-new-dev-live-publ-295647976.us-east-1.elb.amazonaws.com"
        /port "7000"
        }
 

Virtualhost configuration:

<VirtualHost *:443>
    ServerName aempublish.com
    DocumentRoot /opt/aem/cache/

    ProxyPreserveHost On
    ProxyPass / http://10.227.230.195:7000/ retry=1 acquire=6000 timeout=600 keepalive=On
     ProxyPassReverse / http://10.227.230.195:7000/

    <Directory "/opt/aem/cache/">
        Require all granted
    </Directory>

    # Additional Dispatcher or cache configs here as needed

    <Directory /opt/aem/cache>
        AllowOverride None
        Options FollowSymLinks
        Require all granted

        <IfModule disp_apache2.c>
            SetHandler dispatcher-handler
            ModMimeUsePathInfo On
        </IfModule>
    </Directory>

RewriteEngine On
         RewriteRule ^/$  /content/aem/global/en_us/home.html [PT,L]

</VirtualHost>

Even without Including the VirtualHost config still by default the call is going to :7000/content/we-retail.html

Thanks in advance. Appreciate your inputs on this issue.

Hi @VikramP8 ,

Your AEM Publish instance must know it’s behind HTTPS (via the dispatcher+ALB). You need to pass the right X-Forwarded-* headers, and configure AEM to honor them. Try to pass additional headers:

RequestHeader set X-Forwarded-Proto "https"
RequestHeader set X-Forwarded-Port "443"
RequestHeader set X-Forwarded-Host "aempublish.com"

or

RequestHeader set X-Forwarded-Proto "http"
RequestHeader set X-Forwarded-Port "80"
RequestHeader set X-Forwarded-Host "aempublish.com"

Hi @konstantyn_diachenko 

I have added the request header details as well. But still experiencing the same.

Thanks

@VikramP8 if this is happening even without Vhost config,  i feel issue is somewhere in your publisher..

Have you checked your externalizer "Day CQ Link Externalizer"  or etc maps ? How's is it configured?

Publish domain should not contain port

Hi @Shashi_Mulugu 

below are the configurations setup in the externalizer

local http://localhost:7000

publish https://aempublish.com

Thanks

Thanks @Shashi_Mulugu. Issue was with one of the etc mappings which was rectified and it resolved the issue.

Hi @VikramP8 ,

Try removing the port from 

ProxyPassReverse / http://10.227.230.195:7000/

Try using it like this

ProxyPassReverse / http://10.227.230.195/

Thanks
