Re: Forwarding request to a different servlet

2023-08-13 Thread Andy Pont 

I wrote...


Progress of sorts!  The request is now returning 302 instead of 404!

Looking in the log files for the backend, it has a message that says “Robot 
requests must be rejected” and the 302 response is due to a redirect to a 
permission denied page.

My understanding was the .forward() method didn’t change anything on route in 
either direction.
Using JD-GUI I have looked at the class that is generates the above 
error message and it appears as the result of a check on the 
“user-agent” setting.  I am now puzzled as what is being received by the 
backend servlet is the same as if it is called directly without me 
intercepting it.


The class I looked at contains a definition of a valid non-robot 
user-agent string.  Is it possible to modify the request to use this 
before forwarding it?  If not, am I better creating a new request for 
the backend and copy HTTP header and body content around as needed?

Java Connector help needed

2023-08-13 Thread Charlie DiDonato 
Hi All,
I am migrating from tomcat 8.5x to 9.0.78

Below is my server .xml

I don't have Apache webserver fronting this yet on my local machine (Windows
10).

It is a Java app.

 

Here is the part that I feel is relevant, but the full config is listed
below that.-

I order to see that tomcat is working without Apache WS, do I need to also
create an HTTP1.1 connector in addition to AJP connector?

And what should happen when I define a redirectPort ?

And finally, how do I access tomcat URL to hit tomcat and bypass Apache WS?

Thanks

Charlie DiDonato

The browser only speaks HTTP protocol. So yes, if you want to bypass Apache 
Frontend-server you need an http connector on tomcat side.

The redirect Port is only used, when Tomcat needs to redirect HTTP to HTTPS.
If you only use HTTP or only HTTPS, this attribute is not used.

This depends on your infrastructure. You can use a separate http(s) port. E.g. 
80/443 is used by Apache and 8080 is used by Tomcat.
Then you can used http://:8080/ to access Tomcat directly. Of 
course, firewall etc. must allow this traffic.
