tons of "remembering recent failure for XXX seconds" lines

[Dennis Jacobfeuerborn]

Hi,
I'm trying to get mod_pagespeed to work for the Apache httpd and while the module itself seems to work fine it seems to have problems with even trivial stuff.
I've create a folder "test" in the document root with a trivial index.html file but when I access the test folder in the browser I get the following entry in the log:

[Thu, 28 Jul 2016 11:14:49 GMT] [Info] [32374] HTTPCache key=http://<subdomain>.<domain>/test/ fragment=<domain>: remembering recent failure for 280 seconds.

What is mod_pagespeed trying to tell me with this? What failure is it talking about?

Regards,
  Dennis

mod_pagespeed is trying to tell you that it failed to fetch a resource from a webserver via http.

When mod_pagespeed fetches a file, it mentions "mod_pagespeed" in the user-agent header, which should show up in the access logs.

Assuming that the fetches target a server you have access to, the target webserver's access logs may tell you more about the specific failure that mod_pagespeed ran into. 

Also, for static files, mod_pagespeed offers an alternative to http fetching: loading files directly from disk:

I also want to point out that the message you pasted is an "Info" message; it doesn't necessarily indicate anything is wrong.  mod_pagespeed is just logging it tried to fetch that file and couldn't find it.

Hi, I get the same message like crazy on the logs. I know it's only an info message, but a lot of my resources are not being optimized and when I check the logs, this is the message I get for those resources.

A probable cause is that mod_pagespeed is unable to use an HTTP fetch from your server to find the resource.  This might be due to your DNS setup.  A remedy is to map origin domains:

https://developers.google.com/speed/pagespeed/module/domains#mapping_origin

or to have mod_pagespeed load resources directly from the file system:
