Tomcat 8.0.38
In my Eclipse development environment when particular servlet requests are made
I want to simulate going through Shibboleth prior to Tomcat handling the
request. I wanted to see if this will work.
In Eclipse within each dynamic web application I would add a valve to the
context.xml file.
The valve would:
1) Check the URL request.
2) If the URL string matches a list then it will add particular name value
pairs to the request.
Example of a possible valve:
<Valve className="my.valves.ShibbolethSimulationValve" />
1) Can a valve actually identify a particular URL path?
Yes. Valves have access to Tomcat's internal request and response objects.
2) Can a valve add an attribute to the request prior to the servlet
getting the request?
Yes.
Apologies for barging in. Does that mean that, at this point, the request is still
"mutable" ? (at the servlet filter level, it isn't, as far as I know).
3) If item #1 and #2 will work does anyone have some base code for a value
that would get me started down the correct path?
Have a look in the org.apache.catalina.valves package. SemaphoreValve
and CrawlerSessionManagerValve should give you an idea.
Note that you can also do all of the above with a Filter that isn't
Tomcat specific and would, therefore, be usable with other containers as
well.
