Hi, I just implemented virtual hosting on our web server combining multiple virtual hosts and localization as described in the corresonding how-to. But it's very (very) slow. How can I speed it up? Following the External Python Method I used for the Access Rule: import string def get_language(self, REQUEST): cookie = 'LANG' if self.REQUEST.cookies.has_key(cookie): lang = self.REQUEST.cookies[cookie] else: langs = string.split(self.REQUEST['HTTP_ACCEPT_LANGUAGE'], ',') for lang in langs: lang = string.strip(lang) if lang: lang = string.split(lang, ';')[0] break if not hasattr(self, lang): if string.find(lang,'-')>=0: lang = string.split(lang,'-')[0] if not hasattr(self, lang): lang = 'de' return lang def localize(self, REQUEST): sitemap = { ... } hostname = string.join(string.split(string.lower(string.split(self.REQUEST['HTTP_HOST'], ':')[0]), '.')[-4:], '.') lang = self.get_language(self.REQUEST) stack = self.REQUEST['TraversalRequestNameStack'] if stack and stack[-1]=='Z': stack.pop() self.REQUEST.setVirtualRoot('Z') else: if sitemap.has_key(hostname): self.REQUEST.set('SiteRootPATH', '/') self.REQUEST['TraversalRequestNameStack'].extend([lang, sitemap[hostname]]) else: self.REQUEST.set('SiteRootPATH', '/')
