Forum OpenACS Development: Error: return: failed to redirect

So when you get an HTTP request for a file that does not exist, it redirects to the file specified for NotFoundResponse, can't find it, and redirects to the file specified for NotFoundResponse, until it hits the redirect recursion limit.

The file should be under openacs/www/global/file-not-found.html according to your configuration.

You can check the access logs to correlate the 404 request in the access to to the not found response you see in the error log.

That is what i thought as well. But i have two more oacs boxes running under the same aolserver instance. Those are mirrors of the one that got the error and they have no errors at all. Thank GOD! I guess if the problem was aolserver the error would show up on them too. Or maybe not, depending on what broke in AOLServer i believe.

So, I followed you and I debugged and compared the config.tcl with the current one availlable on CVS HEAD. Everything seems fine.

I also tested some pages: static such as robots.txt and dinamic such as adp and tcl pages. Everything seems fine again.

Then, Eureka!
Dave, you gave me a good intuition. I checked access logs and compared it against the error at error.log.

i saw this line bellow repeated many times:
[10/Sep/2009:23:07:16 -0700] "GET /project-manager/fred-dispatch-development/?project%5fitem%5fid=2548 HTTP/1.1" 200 89135 "http://iurix\

Their log time match and that caught my attention. So, i reinstalled project-manager and the error is gone!

Although, this error is weird to me. It means that aolserver is locked up with project-manager application.
Or even worst, pm did something bad to aolserver installation. But those are just ideas. I need to debug it

To reproduce the error just visit some wrong url (eg. https://openacs.org/a.css )

I have the default config parameters:

#
# Special HTTP pages
#
ns_param NotFoundResponse "/global/file-not-found.html"
ns_param ServerBusyResponse "/global/busy.html"
ns_param ServerInternalErrorResponse "/global/error.html"

ns_section ns/server/${server}/redirects
ns_param 404 "global/file-not-found.html"
ns_param 403 "global/forbidden.html"

You can reproduce the error in a fresh openacs install.

Thanks for the help,

Best Regards

It's working for at least one aolserver 4.5.1 on freebsd using this in nsd.tcl:

    # Special HTTP pages
    #
    ns_param   NotFoundResponse   "/global/404.adp"
    ns_param   ServerBusyResponse "/global/busy.html"
    ns_param   ServerInternalErrorResponse "/global/error.html"
