Hello everyone, I'm currently working on porting an application to using the Google App Engine, but I've run into a very odd bit of behavior. Sometimes I need to redirect to a site that expects query strings to be in EUC-JP instead of UTF-8, and self.redirect() doesn't set the location correctly when I try to do so. Here is the incorrect behavior, which only occurs when run on the cloud:

I have not tried the above cmd value before, so I know it's not in memcache: content = url_parse(row.content, cmd, argv, cmb) content = content.replace(' ', '%20') content = content.encode(row.encoding) self.response.headers['Cache-Control'] = 'max- age=172800' memcache.set(digest, content, 3600) self.redirect(content) row.encoding = 'EUC-JP' in this case. If row.encoding = 'UTF-8' (the default) the behavior on the local and cloud instances is the same. What can I do to get the redirect working when Location can't be UTF-8?
