Subject: New page redirection method
Hello,
in my recent test with UNB 1.6 in PHP5.1/FastCGI with the APC cache, which worked all fine by now, I found one problem in the current UNB code: The page redirection sends a "Status: 303" HTTP header, besides the "Location" header, to signal search engines, bots or whatever that this is a special kind of redirection, not a temporary or an error kind. Sending this HTTP header caused my local web server setup to show an error message complaining about a duplicate HTTP header. So I watched a little around and changed the "Status: 303" header to a "HTTP/1.1 303 See other" header. This seems to work fine in PHP5.1/FastCGI, PHP5.1/CGI and PHP4/CGI for now. But I'm not so sure about the HTTP 1.1 part. I've heard some web proxies still use HTTP 1.0 or something.

I've now updated the UNB version on this site, so could you please test if that kind of redirection works for you? The easiest way would be to submit a form like the login, the settings page or a add/preview a posting - not the search form. Preferably using a web proxy. Please tell me what your results were. Thanks in advance.

If anybody knows a better solution for sending status codes with a FastCGI server, or detect the environment, please let me know. :)

I expect UNB 1.6.1 to be released sometime in January. There have been some fixes since 1.6 already.

I don't know if I did right, but these are my results. Using a server that connects via proxy AFAIK, loggin in and previewing a post works just fine. The only thing is that when loggin in with the standard info "Name/ID" I get a 404: The requested URL /forum;err=2;name=Naam/ID was not found on this server.

And I used http://proxify.com/, but I'm not sure if that is what you meant? Then I get only plain text..

I don't know what that proxify thing is, but it apparently cannot handle XHTML websites. Not sure how wide spread they are on the underground pages. ;)

The 404 error seems to be a more general problem with "/" characters used as URL parameters. I'll investigate this.

Additional question: Have you set something like "use HTTP/1.0 for proxies" in your web browser? Should be near the "use HTTP/1.1" setting.

Indeed :)

Hmm, I can't find an option like that in Firefox 1.5 or IE 6 I have running here. In Opera I have such an option, but there seem to be problems with the proxy... Will try it next week, then I have contact with the network systemadmin of that server.

Firefox 1.5:
Go to the address "about:config" and look for the setting "network.http.proxy.version". It's "1.1" for me. Maybe using a proxy and setting it to "1.0" makes problems. I have no proxy here to test this.

Internet explorer 6:
Menu "Extras", "Internet Settings", Tab "Advanced", Group "Settings for HTTP 1.1", Option "Use HTTP 1.1 for proxy connections". It's disabled on my system.

Maybe a HTTP 1.1 capable browser doesn't even care if the server reply uses a newer protocol than the request was? And browsers that can be used with UNB should understand HTTP 1.1 in any case. ;)
