Page Loading Speed And Meta

Recommended Posts

Hello, I posted the same question a few weeks ago, I think it may have got deleted because of the code in the post, so I won't put any this time.

I use some meta tags to keep the page from caching, like "no cache" and the tag that tells browsers not to save any data.

 

DO these type of tags slow the loading of a page? Are they necessary, for instance if I post a new news article or something and someone who visited yesterday comes back will they see the new content?

 

Thank you

Putting a 'no-cache' meta tag in your page could slow the loading of your page a little when a visitor views your page again and it had not changed. Because the page would not be cached on the first visit, a second view of the page would result in the server re-sending the same page again instead of the browser retrieving it from the local cache.

For what you described, I don't believe you would need a 'no-cache' meta tag. The default settings for Internet Explorer, for example, automatically check for a newer version of a page if the page was last viewed in a prior session of IE, or on a previous day. In the case you describe, IE would display the new content since the page was last viewed on a different day and most likely a different session of IE.

Thanks for the info, I think I will remove the tags.
