this is relevant for some QR-Code Applications where capital letters give an advantage of possible link length like this one: http://de.wikipedia.org/wiki/QR_Code#Design-QR-Code the code links to HTTP://DE.M.WIKIPEDIA.ORG this is sometimes answered with: * "Scripts should use an informative User-Agent string with contact information, or they may be IP-blocked without notice. " * With a Wikimedia file not found * With the expected webpage like decapitalized link it seems to depend on either the user-system (e.g. Android) or the user-network. Could it have to do with the server(s) configuration (rewrite-rules?)
(In reply to comment #0) > * "Scripts should use an informative User-Agent string with contact > information, or they may be IP-blocked without notice. " This is done because there is no UA provided. See Bug 28884 and http://meta.wikimedia.org/wiki/User-Agent_policy > * With a Wikimedia file not found What is the URL that gives this result? > * With the expected webpage like decapitalized link When do you see this? It sounds like you're getting different results depending on the platform you're using (e.g. Android, etc). In that case, this is probably a problem with your application.
could it be that some systems decapitalize the URL before sending it and it therefore seems as if it was working? HTTP://DE.M.WIKIPEDIA.ORG does not work with standard Android browser... iPhone, Win32 Firefox and Explorer all work fine
This definitely doesn't look INVALID to me -- reopening. I see a cached result "Scripts should use an informative User-Agent string with contact information, or they may be IP-blocked without notice." when following the link above -- even if I manually rekey it to http://de.m.wikipedia.org/ This indicates that there's a cache-poisoning problem; something or several things along the pipeline are failing to properly validate things?
Created attachment 9276 [details] Screenshot on my Nexus1 showing bogus page loading http://DE.M.WIKIPEDIA.ORG/
Created attachment 9277 [details] Screenshot on my Nexus1 showing ok page loading http://de.m.wikipedia.org/
Created attachment 9278 [details] Screenshot on my Nexus1 showing intermittent "user-agent" error loading http://de.m.wikipedia.org/ While the "no such wiki" page shows up regularly when loading the uppercase form in the Android browser, when loading the regular lowercase form both there and on the desktop I intermittently see this error: "Scripts should use an informative User-Agent string with contact information, or they may be IP-blocked without notice." Seems to show up after getting a capital bogus hit, but not always, so not sure if it's from the same thing doing partial cache-poisoning or if it's another problem.
