Hi,

I have seen this type of 404 error happening intermittently:

<html>
<head>
<title>Not Found</title>
</head>
<body>
<h1>Apache server with mod_pagespeed</h1>
OK
<hr>
NOT FOUND:http://mikewills.me/blog/links-for-2011-02-24/
wp-content/themes/richardshepherd-TwentyTenFive-a8f2860
/style.css.pagespeed.ce.pAcUzu9T3K.css
</body>
</html>

Can you give me any more information on what this means? Does it mean
it cannot find a file in cache or anything more specific?

I'm not sure where the "Apache server with mod_pagespeed" string comes from.

The URL reported as not-found is definitely generated by mod_pagespeed.  The first possibility that comes to mind is that you have a multi-server system and not every server has mod_pagespeed installed.  Is that a possibility?  In that case, mod_pagespeed might rewrite HTML and change references to URLs (e..g style.css) to a cache-extended version.  If the browser's ensuing request for  the CSS file winds up a on a different server than the HTML file, and that server does not have mod_pagespeed installed, then it won't be able to decode the resource name to find the CSS file.

Is that a possibility?

That is not it, I do not have a multi-server system. I am running
0.10.19.5 and this is only happening to me on https pages, I do have
this directive:

ModPagespeedMapOriginDomain http://www.domain.com https://www.domain.com

and my experience with https pages is that they usually need a couple
refreshes to finish optimizing the resources but sometimes a resource
will throw a 404 and when I open it up I get that special
mod_pagespeed 404 message. I do see it in the code here:

http://www.google.com/codesearch#kGe7pYmmq7E/trunk/src/net/instaweb/apache/instaweb_handler.cc&q=%22Apache%20server%20with%20mod_pagespeed%22%20package:http://modpagespeed%5C.googlecode%5C.com&l=95

Any other ideas?

+1 for this old thread... this is still happening with current mod_pagespeed installed in Apache server... there is random 404 errors when loading images and javascript files... very weird

What's your URL?
What version of mod_pagespeed?
How did you configure it?
Anything interesting showing up in your Apache error log?

We're having similar issues. Through checking the logs, it turns out that some requests arriving on port 80 are incorrectly modified to port 443 by (I'm assuming) mod_rpaf which we're also running. This in turn means that mod_pagespeed fails to find the resources because it treats the url like it were https:// instead of http://. The appearance is intermittent 404s, but the apache error log shows requests with https:// when in fact the original request was http://.

I'm guessing it's related to mod_rpaf. I've tried disabling (but not uninstalling) mod_pagespeed and the problem continued. It only happens on our production server, not on our staging server, despite identical setups (mod_rpaf versions, mod_pagespeed versions, apache versions, config, etc...).

I'll try to post back when I find a solution.

Cheers - Callum.

Our issue turned out to be this https://github.com/gnif/mod_rpaf/issues/12

In a nutsheel, mod_rpaf can't properly rewrite the port. There is a workaround, which we're now using. I guess there's something in mod_pagespeed about requests on port 443 being served over HTTP causing an issue.

Cheers - Callum.

This issue seems to be already alive. I guess that i'm suffering this on my server. I've mod_rpaf installed and latest mod_pagespeed. So, there is no fix already for this? There are another alternatives to mod_rpaf that solves this issue??

hi my friend i am not sure if this is still alive  
my url  is https://www.biomedicus.gr   

this is the log error

Hi -- it seems like you've been reporting the same in a number of different contexts. It probably makes sense to try something really simple.

If you make a simple test web page with a single image, does mod_pagespeed successfully rewrite that image's URL and serve it? If not, let's get that to work.  It might be worth reading the FAQ and also the https support doc pages.

it seems that no one can help us.. the images arent served correctly not sure why, after 2 days they disappear. i dont have the knowledge to debug it even if i read the faq file.  
the only option i read is to deactivate mod rewrite images but it affects the site speed i believe

It sounds like the module has trouble fetching its input resources (css / js / images). 
Reading up over at the pages Josh linked earlier should help.

i removed the rewrite_ image filter  but still some pictures are vanishing    

if you visit  in incognito  in the homepage  there is a photo down missing https://www.biomedicus.gr

does this filter removal from pagespeed affect the loading time ?

Hi Biomedicus

I find that you have some problem w/ cherry-framework. You had enabled the inline_css filter, when I disable it, all images se rewrited and loaded.
I have tried https://www.biomedicus.gr/?PageSpeedFilters=-inline_css,+rewrite_images. -inline_css to disable this filter and +rewrite_images to enable that because you don´t have enabled it.

thank you for your reply, so i go to pagespeed.conf  and you want me 
1. to disable the inline_css filter  in the pagespeed.conf
2. to enable to rewrite images filter in the pagespeed.conf
? 

is that correct?? 

p.s. i disabled the rewrite image because it caused me too much trouble and i saw it as the only way out.  
i use smush plugin and fast velocity minify. can these cause any trouble?

Yes. I found that disabling inline_css filter the rewrite_image filter work. I think you don´t touch any other plugins/setting and try only these 2 things. When you have the site working w/ pagespeed module, you can try other config, like disabling the plugin and trying others pagespeed filters.

As far I can see, no images are getting the 404 code error, and in chrome all are converted to webp format..... thus I think the pagespeed module is working.

Hi -- I think you need to start simple and see if things are working, then add in the complexity of your site and environment. It will make debugging much easier.

Can you, temporarily, turn off the whatever other tool you have that's optimizing your site? Two reasons:
  • the functions that you showed in the screenshot of the settings dialog are all covered by PageSpeed as well.
  • multiple tools that alter your web page to make it faster may get into each other's way, even if each one works by itself. 
Also, as I suggested earlier, I'd start by writing a very simple web page with one image in it and make sure that works with mod_pagespeed. Then move on to complex functionality like uploading photos.

That is likely to be easier to integrate for you, yes. It will not optimize as much.  More generally, see 


By using the option you found, you limit the ability of PageSpeed to optimize images for the size at which they will be displayed, but it will still optimize them and even transcode them to webp. So it's probably a good compromise given that you have a lot of complicated things going on on your site, in particular other optimization engines.

Hi -- it sounds like there may be a problem fetching resources over HTTPS in your setup. Making sure you've configured HTTPS fetching properly is the next step.  Can you look over https://www.modpagespeed.com/doc/https_support and make sure that's working?

By 'check that it's working' I mean that a page that contains one image appears correctly in the browser, and has its HTML (use browser's View->Source command) has the rewritten image URL with ".pagespeed." in the name, and that it gets served without a 404. I'd check that in your browser with (e.g.) Chrome developer Tools.

I'd also look in the apache error.log to see if PageSpeed is complaining about anything when viewing that page.


However, I think it also makes sense for you to try OptimizeForBandwidth and see how it goes. That may meet your needs without you having to poke around the system as I've suggested.

Hi Biomedicus
Near this line:

    # The locations of SSL Certificates is distribution-dependent.
    ModPagespeedSslCertDirectory "/opt/bitnami/common/openssl/certs"
    
Add this:
   ModPagespeedFetchHttps enable
   ModPagespeedSslCertFile file
   ModPagespeedDomain http*://*.biomedicus.gr

where file is a cert.pem usually in /opt/bitnami/common/openssl/certs

This is needed by pagespeed to fecht resources in https.
You can use this too:

    ModPagespeedLoadFromFile "https://www.biomedicus.gr" "/var/www/example/"
    ModPagespeedLoadFromFileRuleMatch  Disallow *
    ModPagespeedLoadFromFileRuleMatch allow  \.(js|css|jpg|jpeg|png|pdf|gif)(\?.*)?$

This can load static files from disc w/o fecht it by https.
/var/www/example must be your root directory and js,css,...etc must be the file extension you will load directly from disc.

Thanks Longinos. Biomedicus, I agree that looks like the right next step. PageSpeed will be much more effective if it can pull your resources, and HTTPS fetching needs to be configured as Longinos describes in order to work.

hi josh and longinos 

i think somewhere here is the solution.   i read that pagespeed server by default from http  


i followed some hours ago the faq document and  put   this in pagespeed 

ModPagespeedMapOriginDomain "http://localhost" "https://www.example.com"
the photos appeared again but dont know for how long that is why i am not celebrating anything.   
should i put in pagespeed.conf also what longinos is proposing?

Hi
This
ModPagespeedMapOriginDomain "http://localhost" "https://www.example.com"

can be set if you have a web server in http://localhost and need to respond as https://www.example.com.

And, yes, you need to complete, all most, the https config, as far as your config is incomplete.
Pagespeed on default work on http so you need to configure it for https. Think in the certificate file and directory same as a browser, if don´t have certificates
configured on browser cannot reach https sites.
And you need to authorize the https domain, because if not, pagespeed only fecht http resources.

The LoadFromFile is to bypass https fecht on static resources like js,css or image files. If the disc system has a good response time is better than fechting 
resources via https request.

hi longinos , 

do you want me to apply the other suggestion as well? 
that means do you want me to apply 

Near this line:

    # The locations of SSL Certificates is distribution-dependent.
    ModPagespeedSslCertDirectory "/opt/bitnami/common/openssl/certs"
    
Add this:
   ModPagespeedFetchHttps enable
   ModPagespeedSslCertFile file
   ModPagespeedDomain http*://*.biomedicus.gr

where file is a cert.pem usually in /opt/bitnami/common/openssl/certs  ????


i have only added  the ModPagespeedMapOriginDomain "http://localhost" "https://www.example.com"  but the load time is slightly slow, but the photos are still here. we need this to confirm tomorrow

Yes, I suggest you to do that. Your https config is not complete.
You need enable the https fecht => ModPagespeedFetchHttps enable
You need a vertificate file => ModPagespeedSslCertFile file. You had configured a path, but not a file name.
You need authorize the https domain, pagespeed by default only auth the http domain => ModPagespeedDomain http*://*.biomedicus.gr
In this form you have auth the http,https and all subdomains in both protocols.
All these directives are a must have, is a complete config.

With the LoadFromFile part, well is animprovement that you can use or not, but if you have a fast disk is better.

hi longinos , 

i insteted in pagespeed.conf 

ModPagespeedFetchHttps enable
ModPagespeedSslCertFile /opt/bitnami/common/openssl/certs
ModPagespeedDomain http*://*.biomedicus.gr



 

i changed the language of the site and it broke again ,  then i entered all the above and it showed the photos again , not sure for how long this time.  

2.  how can i use loadfromfile??   the code in faqs is like this 
ModPagespeedLoadFromFile "https://www.example.com" "/var/www/example/static/";
so i change it to this and enter in pagespeed.conf ???
ModPagespeedLoadFromFile "https://www.biomedicus.gr" "/var/www/biomedicus/static/";  
??
