Hi,

My set up is as below:

NGINX (reverse proxy) IBM WebSeal (redirects to a common login page,  
after  
authentication forwards to internal proxy along with the redirected url)  
  
Internal Proxy (IBM http Server)  WebSphere Portal.

I am trying to access  
https://\<host\_name\>/wps/seedlist/myserver?Source=com.ibm.lotus.search.plugins.seedlist.retriever.portal.PortalRetrieverFactory&Action=GetDocuments&Range=100&locale=en

Host\_name is the server\_name on NGINX and the url is in the Portal  
server.  
When I am accessing it directly, replacing the host\_name with Portal  
server  
IP/port, it works.

With the host\_name, I am getting the message as in the subject line, on  
the  
browser.

My nginx config is below:-

#Security  
server\_tokens off; #Turn off version number  
add\_header X-Frame-Options “SAMEORIGIN”; #Turn off click jacking; so  
no  
frames  
add\_header X-XSS-Protection “1; mode=block”;  
add\_header X-Content-Type-Options nosniff;

# Redirect all insecure requests to the secure port

server {  
listen \<IP\_address\>:80 ;  
server\_name ;  
return 301 https://\<server\_name\>$request\_uri;  
}

# Serve SSL encrypted data

server {  
listen \<IP\_address\>:443 default\_server ssl;  
add\_header Strict-Transport-Security max-age=15768000;  
server\_name \<server\_name\>;

access\_log /web/nginx/servers/name/logs/access.log;  
error\_log /web/nginx/servers/name/logs/ error.log;

# Security

# Specify the certificate and key

}

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;

proxy_pass http://<webseal_hostname>/;
proxy_read_timeout 90;

```

}  
}

Please help.

Thanks,  
Krishna
