Routing subdomains in Apache Tomcat - apache

I have 2 subdomains for my domain: "www" and "hosting". I made 2 WAR applications: one for the "www" site, and another for the "hosting" site.
Is there any way I can configure Tomcat 7 to route subdomains to web applications?

Reverse Proxy set up would enable finer control over how the HTTP requests are handled and directed. You would configure the proxy for each of the subdomains to point to the proper applications.
I use nginx as a reverse proxy in front of my Tomcat webservers.

How to use Apache to redirect requests for Node-Red?

I'm running in AWS a Ubuntu with a docker server (managed by Portainer) with this two running containers:
1 - NodeRed (Serving my APIs)
2 - Apache (Hosts the site that consumes the APIs from NodeRed above)
I've configured a domain to this server and setted apache to work with SSL. The apache is running ok with my site through HTTPS, but the problem is that the NodeRed (that runs in port 1080) is not configured to run in SSL. This causes a malfunction in my website since that my API endpoints are being running under HTTP and being blocked by the browser due security reasons.
The question is: is there a way to create some kind of "mapping" in apache that receives the request from HTTPS and redirect to the NodeRed in HTTP (the two are running in same server)?
My idea is to create a subdomain like https://api.mysite.com that sends the request for apache and then apache redirects it to my NodeRed. Is that possible?
There is no need to expose the API to the outside world if you don't want to. Since your apache is running correctly and both containers are running on the same host, just use proxy to forward API requests to the API container.
You can achive this by add two lines to your apache config i.e.
ProxyPass /api/ http://127.0.0.1:1080/
ProxyPassReverse /api/ http://127.0.0.1:1080/

apache redirect to SSL configured site

I am trying to setup a gitlab repository and I am quite new to the web server side of things. My setup is the following:
I have an apache server which is running my main website on port 8080.
I have the gitlab configured with SSL and Nginx and running on port 2443.
At the moment, the gitlab site can be accessed through https://www.example.com:2443.
What I would like to do is setup a redirect through my apache server where if someone comes to http://www.example.com/gitlab or https://www.example.com/gitlab, they get redirected to ``https://www.example.com:2443` (preferably without the web browser text field changing).
Could this be done easily with Apache? Also, since the redirect is to an SSL site, any special things we need to consider?
You can try adding the redirect directive to your Apache VirtualHosts (8080 and 443).
Redirect permanent /gitlab https://www.example.com:2443

SSL on Jelastic and Jetty 9

I created Jelastic environment with Jetty 9. Then I added SSL support - Jelastic created NGinx instance and my solution now available using https and provides certificate. Question is - how to deny access on old non secure way? I mean using ordinary http?
You just need to edit the nginx config. to redirect http requests to https.
Example configs:
NGINX Redirect http to https and non-www to ww

How to get tomcat to send redirects as https urls when apache handles ssl

I'm a bit out of my depth here and nothing I have found quite addresses my problem. Si any and all suggestions are most welcome.
I've got tomcat6 running on CentOS 6.5 hidden behind an apache server (v2.2.15) and I am using Apache's mod_proxy to expose the tomcat webapps, which are running on port 8080. The tomcat hosts one production application and several development applications. On the apache side, both a Drupal site and the aforementioned tomcat production application are on the same domain and, thanks to rewrite rules, all requests to this domain are changed to https. The development sites are reached via subdomains and do not get re-written as https requests.
For the most part, this arrangement works fine. But parts of the tomcat apps are AJAX (calling a Java Struts 1.2 backend). Most of those requests are handled OK. But a few AJAX requests result in redirects (i.e., forward.setRedirect(true)) and that redirect is http (I guess because the container itself is not secure). As a result, I run into cross site scripting issues. I imagine I can use CORS headers to avoid the problem. But that seems like a hack. Is there a relatively painless way I can use to have tomcat send redirects back as https without making tomcat handle ssl directly?

You could configure the RemoteIpValve in Tomcat:
Another feature of this valve is to replace the apparent scheme
(http/https) and server port with the scheme presented by a proxy or a
load balancer via a request header (e.g. "X-Forwarded-Proto").
To configure Apache to forward the original protocol in the X-Forwarded-Proto header, add a RequestHeader directive in your Apache config, e.g.:
<VirtualHost *:443>
RequestHeader set X-Forwarded-Proto "https"
...
Note that in Tomcat 7, there is also a RemoteIpFilter.
You don't need to do anything special. It already works. Make sure you set the "redirectPort" in server.xml to Apache's HTTPS port, usually 443, and add the following to your <security-constraint> sections for resources you want secured by HTTPS:
<user-data-constraint>
<description>HTTPS</description>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</‌​user-data-constraint>
Late to the game here but others may find this-- we had a similar setup and issue where everything worked fine until the application started using ajax posts which did redirects for the response. The fix was to use mod_header in apache to rewrite redirects using "Header edit Location"
http://httpd.apache.org/docs/current/mod/mod_headers.html
Header edit Location ^http://www.example.com/ https://www.example.com/
This went unnoticed prior to the ajax redirects because the browser has no problem doing page level redirects to http (which apache would then redirect back to https). But the ajax cross-site prevention halts at the initial http missing out on that would then be redirected to https by a subsequent request.

Make tomcat redirect to another server with the same domain

I have a domain name and a tomcat server so when I deploy an application on it, this is accesible via my.domain.com/MyApp and everything is fine.
The problem is that I have some applications I can't deploy on my tomcat server and i think i'll have to make another tomcat server to deploy them and when I type my.domain.com/MyNEWApp I want to be redirected to the new server but i don't know how to do it or if there is a better solution for my problem.
Place your Tomcats behind a content-switching load balancer or a reverse proxy (e.g. Apache with mod_proxy, mod_jk or mod_cluster) and point the my.domain.com domain to the LB. Then on the LB, route traffic to respective Tomcats based on the context root.
