Apache 2.4 and 1.9.32.13-stable #1273

Open salvoaranzulla opened 8 years ago

Hi,

I have seen a strange behaviour from Apache 2.4 and mod_pagespeed 1.9.32.13-stable.

Many times CSS is not rewritten and I see this error:

[Mon, 29 Feb 2016 16:35:48 GMT] [Info] [17746] HTTPCache key=http://www.aranzulla.it/web/themes/sa2014/style.css fragment=aranzulla.it: remembering not-cacheable status for 233 seconds.

This problem happens also with images:

The image http://www.aranzulla.it/wp-content/contenuti/2014/03/Infostrada-100x75.jpg does not seem to exist.

The messages about http://www.aranzulla.it/web/themes/sa2014/style.css not being cachable seem strange. Do you have multiple servers running? If so, do they all respond with the same Expiry and Cache-Control headers for this file?

You are right. We are fixing it.

Do you have multiple servers running?

yes

If so, do they all respond with the same Expiry and Cache-Control headers for this file?

yes. now it seems style.css is rewritten.

Hi,

style.css is on www., and the rewritten resources are on a., do you have different configs for the www. and a. domains?

Hi,

We have same configuration and we use the same server.

Sometimes styles.css is rewritten, sometimes style.css is not rewritten.

I see this error:

if i add ?PageSpeedFilters=+debug to the url, i can see that sometimes "style.css" gets inlined properly, and sometimes it fails to be rewritten. Does style.css reference images which change frequently?

<link href="http://www.aranzulla.it/web/themes/sa2014/style.css <view-source:http://www.aranzulla.it/web/themes/sa2014/style.css>" rel="stylesheet">

Hi,

Expected behaviour is style.css inlined in our page.

Does style.css reference images which change frequently?

No, images are not changed frequently and style.css is not edited frequently.

This is my pagesped configuration, if it can help you:

i can't seem to reproduce on your site any more.

Were you experiencing high traffic volume at the time, or were one or more of your memcached servers down?

Yes, now it seems style.css is rewritten and inlined correctly. Sometimes is rewritten, sometimes is not rewritten. I can't find a pattern of this strange behaviour. The only error I see is:

[Thu, 03 Mar 2016 15:25:05 GMT] [Info] [7938] HTTPCache key=http://www.aranzulla.it/web/themes/sa2014/style.css fragment=aranzulla.it: remembering not-cacheable status for 5 seconds.

We have 400.000 average visitors by day. We don't have any problems with memcached:
