The guys over at 37 Signals posted an explanation of why they think the Google Web Accelerator is a bad idea<\/a> and a link to a page which shows how you can disable the Google Web Accelerator by analyzing HTTP headers using Ruby<\/a>. I’m don’t really care to discuss why you think the GWA is good or bad, but in case you think it’s bad, here’s the same thing implemented as a ServletFilter (here’s the same thing for ColdFusion<\/a>):
\n
\npublic void doFilter(ServletRequest req, ServletResponse res, FilterChain chain)
\n  throws IOException, ServletException {
\n  HttpServletRequest httpreq = (HttpServletRequest)req;
\n  HttpServletResponse httpres = (HttpServletResponse)res;
\n  if (httpreq.getHeader(\"X-moz\") != null &&
\n    httpreq.getHeader(\"X-moz\").equalsIgnoreCase(\"prefetch\")) {
\n    httpres.sendError(HttpServletResponse.SC_FORBIDDEN);
\n  } else {
\n    chain.doFilter(req, res);
\n  }
\n}
\n<\/code>
\nAdd the following to your web.xml:
\n
\n<filter>
\n  <filter-name>gwa<\/filter-name>
\n  <filter-class>com.mycompany.web.filters.GWAFilter<\/filter-class>
\n<\/filter>
\n<filter-mapping>
\n  <filter-name>gwa<\/filter-name>
\n  <url-pattern>\/<\/url-pattern>
\n<\/filter-mapping>
\n<\/code>
\nand you’re good.<\/p>\n","protected":false},"excerpt":{"rendered":"
