cgi-servlet environment parameters
Good morning.
I'm working with Tomcat 4.1.31 and am trying to catch 500 errors for
custom error pages. We host around 400 portals in one instance (kudos to
the developers, by the way, it runs great!)
The idea is that the Perl script would create a site on the fly with
little content in the event of a 500. The original request, then, would
be something akin to http://mydomain.com/portal_a/index.jsp. I've got
the cgi-servlet set up to run a Perl script and have created a simple
JSP that returns
response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR)
to create the 500 for testing. The Perl script is set to pick up the
original URL requested and return some content specific for portal_a.
However, the environment does not seem to contain the URL of the
original request (i.e., REQUEST_URI or PATH_INFO), as below:
runCGI(envp=[{HTTP_USER_AGENT=Mozilla/5.0 (Windows; U; Windows NT 5.1;
en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7, HTTP_ACCEPT_ENC
DING=gzip,deflate, REQUEST_METHOD=GET, AUTH_TYPE=,
HTTP_ACCEPT_LANGUAGE=en-us,e ;q=0.5, SERVER_NAME=harrier.mesas.com,
SERVER_SOFTWARE=TOMCAT, HTTP_KEEP_ALIVE= 00,
HTTP_ACCEPT_CHARSET=ISO-8859-1,utf-8;q=0.7,*;q=0.7,
HTTP_HOST=harrier.mesas com:3233, GATEWAY_INTERFACE=CGI/1.1,

uction35/www/500.cgi, REMOTE_ADDR=10.20.2.65, SERVER_PROTOCOL=HTTP/1.1,
PATH_IN O=, REMOTE_HOST=kengibson100625.mesas.mis, QUERY_STRING=var1=2,
HTTP_CONNECTION keep-alive, SERVER_PORT=3233,
HTTP_COOKIE=JSESSIONID=5065D8892D6F8D0FD891483596

ication/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5,
SCRIPT_ AME=/cgi-bin/500.cgi, REMOTE_USER=, REMOTE_IDENT=}],
command=/private-1/portal/
roduction35/www/500.cgi)
Oddly, adding bogus parameters to the end of the request (var1=2) gets
passed to the cgi-servlet in the QUERY_STRING parameter.
Any help in finding the original request is greatly appreciated.
Thanks
Ken

RE: cgi-servlet environment parameters
Thanks for the quick response. Is there a way to configure the
cgi-servlet that I've missed? The PATH_INFO variable is null in my
scenario; I've split it out from the other parameters below...
runCGI(envp=[{HTTP_USER_AGENT=Mozilla/5.0 (Windows; U; Windows NT 5.1;

Since this is an older version of Tomcat, would you suggest a local mod
to force the PATH_INFO and/or REQUEST_URI? Unfortunately, upgrading
isn't really an option.
Thanks in advance for your help.

The PATH_INFO variable is null in my scenario; I've split it out from the other parameters below... I have just added REQUEST_URI to svn. I have also ported a couple of patches from TC5. You could build it from source but to save you the trouble I'll e-mail you a completely unofficial if it destroys your computer you are on your own updated servlets-cgi.jar directly. I suspect that the PATH_INFO is correctly null. It depends how the cgi is called. Are you using a forward? If so, you may have hit the requirements of SRV.8.4 which mean you see the PATH_INFO of the request to the CGI, not the PATH_INFO of the original request.
