This is just my non-apache two cents.

Yes, I realise it might not be an Apache problem.
But it did start appearing around the time yum gave us a new version of Apache...

- Is your js loaded after all of the libraries? Are you sure?

Yes. I thought it was, and I just thecked.

Following a bunch of CSS files, we have
     JQUery,
     Several other third party libraries, including OpenLayers and Backbone
   JQuery Mobile.

   Our main (1.7MByte minified) JS file
   A 500kByte minified compiled templates file.
     A couple of tiny JS (configuration) files

A40KByte "top level" JS file.

And THIS, last, file is the one that Chrome says times out!

However, I will try re-ordering things, and see if that makes a difference...

- Is your js file one huge file or many little ones? It sounds like one big file.

Mostly one big one. But that isn't the file that times out!

However, I'll try splitting it, too...

And it is straight JS.

You’ve probably already looked at those, but sometimes it helps to have another person chime in.

A js/chrome list might be more appropriate too.

Maybe. I had two vague ideas, and I wanted to see whether anyone else would suggest them:
* The problem is related to a limit on the number of (simultaneous) fetches from a single client, and the new version of Apache has changed that limit, or

* Chrome is picking up an ISP's a proxy configuration that FFox is not, and it is the ISP's proxy that is/was causing the problem.

Subject: Browser differences

We have developed a complex _javascript_ application

There are "a few megabytes" of our own code, plus OpenLayers map handling and jQuery.

We're serving it through Apache 2.2.15-59, which arrived on CentOS 6.9 in mid April.
And everything works well and reliably for us.

But for the last couple of weeks, our client has been experiencing problems starting the application.

The _javascript_ console reports that some _javascript_ files are not loading because "Connection Timed Out" on one of the JS files.

Apache is not logging any errors.

The obvious explanation would be in terms of network connection between him and the hosting company.
But his connection is actually faster than ours
AND he only has problems when he uses Google Chrome: Firefox is fine.

So I'm struggling to think what this can be. Any suggestions?

Our client started having problems at ABOUT the time that yum installed 2.2.15-59.

Has something changed?

Robert
