[Bug 56917] New: Create a configuration to write relative 302
responses instead of absolute
https://issues.apache.org/bugzilla/show_bug.cgi?id=56917
Bug ID: 56917
Summary: Create a configuration to write relative 302 responses
instead of absolute
Product: Tomcat 8
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: ajay.sindwani@gmail.com
Create a Tomcat configuration to force tomcat to write relative location
headers in 301/302 responses instead of absolute location headers.
Purpose:
Today Tomcat always writes an absolute response for redirects per RFC2616
standards. However as many modern browsers support 302s to relative Locations
as explained in https://en.wikipedia.org/wiki/HTTP_location , our friendly
Tomcat application server should allow configuration to write back 302s in the
more friendly form.
The ripple effect of this where applications choose to use this setting, will
be very good for cpu cycles of web servers and load balancers all over the
world. This can greatly reduce the need for ProxyPassReverse in the Apache
web server, and also for URL rewriting happenin in physical load balancers.
See this example where another gentleman has been compelled to recompile Tomcat
to achieve the same thing

Tomcat, being spec-compliant, must maintain spec-compliance.
There are certainly examples of out-of-spec behavior in Tomcat which are
usually controllable via certain configuration options. It seems like this
could be one of them. Patches are always welcome.

Are you sure? If not all clients support it, then you can't remove that
capability. It's one of the awful things about the web: you can't force users
to upgrade. ;)

This would be contrary to the requirements of the Servlet specification.
See https://java.net/jira/browse/SERVLET_SPEC-100 for the request to change
that (and some other stuff).

Both the servlet spec and Tomcat need to be updated then. Tomcat doesn't have
to wait for the servlet spec, unless the update is already accepted.
The expense of doing 302 rewriting can be cleaned from numerous webserver
environments.
