RE: [Webware-discuss] mod_webkit cannot connect using 'localhost'; invokes IPv6

Jim,
From the information you provide I'd say the connection *is*
being made between Apache and WebWare (from mod_webkit to the
application server). At least at the socket level. And likely at
the request level too.
Your message didn't include any content from the WebWare logs
(Logs/{Activity,Errors}.csv) which might be helpful. Also, make
sure you've elected all the debug options in the configurations
so the application server can provide debug messages.
(q.v., line 468 of application.py.)
A quick look at the archives tells me you're not alone on this
problem, however. I searched on "301." Something like your
symptoms have been around since 2000; here's a typical one:
-- http://sourceforge.net/mailarchive/message.php?msg_id=1307195
So, the localhost->127.0.0.1 workaround might be working for you.
Although I did basic connection tests for the workaround in all
combinations of that configuration (in apache, webkit, appserver),
I didn't run the test suites. So it may only be a partial w/a.
I've moved on in my configuration using the patch I mentioned so
it's not convenient to try to match (parts of) your configuration
(including IPv6-related configurations for your Apache compile).
I *did*, however run the test suite on the patch (provided below
in patch(1) format, wrapped a shar(1) archive); but only on my
configuration. (So be prepared to patch -R and make; make install.)
I'm just new to this too, so I may be missing something obvious.
Luckily we're provided with great debugging tools on the
application server side ... starting with Python.
Also, mod_webkit2.c is a good place to insert debug or tracing
messages. Line 420 has a (context-only) instruction just waiting
to be uncommented. And the lines immediately after that one offer
a template for printing some of the other data related to the
request -- which will help you create a context+content tracing.
If you decide to apply the patch, you might as well also make a few
of these changes.
Good luck; let me hear how it goes.
Best,
--Nick

Thanks. I have this same problem. I changed to 127.0.0.1 and now I get
this message in the apache error_log.
