Hello, is there any free online tool that allows website preview (lsomething like a web proxy) without caching DNS and withotu caching. I mean so on next load i can be sure nothing was saved, no cache, trace
When you say DNS cache, no matter which proxy OR service you use; they have a cache which is built for atleast some time. It is better to use google's resolvers and flush the DNS on your local machine. Make sure you have disable the cache for your website if you want the website to show instant updates.
DNS servers down the line will continue to cache records according to their TTL values so this is essentially impossible. If you are running Windows, you can flush your DNS cache like so (run command prompt as administrator): ipconfig /flushdns Your ISP will still cache DNS per the TTL value. You can also reduce this by setting low TTL values for your A records, but more load will be put on the DNS server if you go too far. Also, you can edit your hosts file to preview a site before DNS propagates. In Windows, it is at c:\windows\system32\drivers\etc\hosts and in *nix, it is usually at /etc/hosts
