ImagePreserveURLs Not Working Even With All Filters Disabled

[Kenaz Chan]

Hi,

I've setup a site with `mod_pagespeed` @ https://theyvc.ecpro.net . My main goal is just to compress images and it is working. However `ImagePreserveURLs` is not working and always set to false in `?PageSpeedFilters=+debug`. I understand from this thread that it will not work if we have any image resize or inline filters. However, it doesn't work even after I removed all filters. Below are my current settings:

mod_pagespeed version: 1.11.33

pagespeed.conf: All using default settings, except below:

• ModPagespeedRewriteLevel PassThrough
  
• ModPagespeedEnableFilters recompress_images
• ModPagespeedDisableRewriteOnNoTransform off
• ModPagespeedDomain https://static.ecpro.net
• ModPagespeedLoadFromFile "https://static.ecpro.net" "/var/www/static/"
• ModPagespeedImplicitCacheTtlMs 2592000000
• ModPagespeedLoadFromFileCacheTtlMs 2592000000
• ModPagespeedInPlaceResourceOptimization on
• ModPagespeedImagePreserveURLs on

?PageSpeedFilters=+debug Output:

In what context is that PageSpeed fragment?  Is it in a VirtualHost matching your host?  Or a Directory sccpe?

It is in a virtual host matching my host. I am using Nginx reverse proxy + apache to host many virtual hosts. Attached are my nginx & apache virtual host files. All hosts having similar virtual host files.

Thanks.
