A question on website caching

[TheGuy]

Hi Guys

I client of mine had a wepage designed by a developer. Now they need to upload documents to the website. Then when it's done thousands of people connect to the site and download the documents.

The problem is that when people log in again the page loads from cache and the new documents are not displayed. The people downloading the documents is from different companies all over the world so you can't just tell them all to press ctrl+F5.

Is there a way to force a refresh every time a user connects to the website?

I checked the page source of the site and there is some HTML, CSS and Javascript in there.

What language is the site coded in?

I'm no expert but maybe look into ajax.

<meta http-equiv="expires" content="mon, 27 sep 2015 14:30:00 GMT">


Not bullet proof . Obviously - change the date.

Does this mean that the content will expire after a certain time and the browser will request a fresh copy?

You could try using

<meta http-equiv="pragma" content="no-cache">

This generally is not a server side issue but a client side issue. A quick and easy method is to add the date to the file name. This way the file is always seen to be new and unique (provided that you do not have more than one doc a day. Many browsers ignore meta tags and there is not way to force it.

Yup - but like i said it isn't bullet proof.

or append a querystring to the filename.
you can at least tell what server is being used by viewing the header output of the http response
