网络上的本地主机-通过网络访问时缓存CSS文件且未更新CSS文件

Question

So I am trying to figure out why my localhost app looks different when accessed from another computer, as opposed to the way it looks when I am accessing my localhost directly from my machine.

I am using a WAMPSERVER and I have a PHP app. It seems like when I try and change the CSS of the app, only I can see the changes. When I try and access the app through another machine, by accessing my localhost, the app looks different and some of the styling is the old styling. Also, if I change anything in the HTML, it updates correctly, but I cannot seem to be able to change the CSS - almost as if the network cached the CSS and it won't update it anymore.

I tried:

1. restarting the WAMPSERVER
2. clearing browser cache
3. restarting the PC
4. Flushing DNS cache ( ipconfig /flushdns )

Nothing seems to be working and the only way I can affect the style of the page is by adding inline CSS which is a pain in the butt and I do not want to do that.

Any suggestions will be highly appreciated!

Answer 1

如果您使用的是PHP Framework（Zend，Symfony等），则其中许多都包含了自己的缓存，并且由于您不是从本地地址访问站点，而是自动使用缓存，因此您可能需要清除框架的缓存。

Browsers cache things, and that can be boring.

A way to prevent that is to add a random string in the url where you get your CS, JS, or whatever, like that :

<link href="mystyle.css?t=<?php echo time()?>" rel="stylesheet" type="text/css" />
