This can be easily achieved using the Time-to-live (TTL) values of the Domain Naming Service (DNS) entries of your website.Serving static assets with an efficient cache policy helps improve page load times on repeat visits by storing these files locally in the users browser. You want to minimize the downtime due to the change in ipaddress. You have your site running on an old hardware and want to migrate it to a new upgraded hardware which would result in change of the ipaddress of your site and in turn imply downtime for your site. We're still in control of cache keys and ttl, but if you're interested in that, there. In your codebase, track down any reference to cache()->put(), cache()->remember(), or any other variants, and do the necessary math to convert the expiration date from minutes to seconds (multiply by 60).Laravel-query-cache adds macros for easily caching your queries. A small, but important breaking change in Laravel 5.8 is the switch from minutes to seconds for all cache TTLs.
DNS is used to resolve the site name to the correct ipaddress. The lifetime ttl entered are in seconds here.The users usually use your site name and not the ipaddress to visit to your site. You can pass the ttl in any position along with the other tags. You can enter the ttl as a tag for settings a different lifetime than the lifetime configured in the rache.php config file. Browser caching stores static assets like CSS, JavaScript, images so that the browser can retrieve them from its local cache.Use the middleware along with tags.
The TTL values can be even lower (0, i.e. Usually the TTL for a DNS entry is specified as 3600 sec (i.e. Once the TTL expires, the DNS record will be fetched again from the DNS Server.
Laravel Cache Ttl Update To The
After this, the DNS value is updated on all servers which follow the RFC. After changing the DNS entry, wait for the new TTL value for the DNS entry to be updated. That means, if the previous TTL value was 1 hour, you should wait for 1 hour after changing the TTL values for all the servers to update to the new TTL value.
Not all servers on the internet respect the TTL values of your DNS entry. Usually the TTL for DNS entries is kept between 1 hour and 1 day. However, you don’t want to do that because when you want to change the entry you will have to wait for at least that amount of time before the changes are reflected everywhere, causing inconsistencies in the entries for longer periods of time. Keeping the values always high can reduce the load on your DNS servers. Also, you can keep the TTL values low all the time, however, this will increase the load on your DNS servers and hence, it is not a good practice. If something goes wrong, or you want to change the DNS entry again, then follow the above steps again to update the DNS record.In this entire process the values of your DNS entry are inconsistent only for the new TTL values that you had lowered it to.
