pagespeed MapRewriteDomain giving 404's on image rewrites

[jerod moore]

Im not sure if this is a bug or a config issue. Seems like it would be a common use case.

 

## PageSpeed configurations
pagespeed FetchHttps enable,allow_self_signed;
pagespeed MaxCacheableContentLength -1;


## Resource filters
include apps/pagespeed/resource_filters.conf;


## Miscellaneous
pagespeed EnableFilters add_instrumentation;
pagespeed EnableFilters insert_dns_prefetch;
pagespeed EnableFilters prioritize_critical_css;
pagespeed EnableFilters collapse_whitespace;
## Cache
pagespeed EnableFilters extend_cache;
pagespeed EnableFilters extend_cache_pdfs;
pagespeed EnableFilters local_storage_cache;


pagespeed EnableFilters rewrite_images;
pagespeed MapRewriteDomain https://mydomain.com/img http://ep.yimg.com;
## Ensure requests for pagespeed optimized resources go to the pagespeed handler
## and no extraneous headers get set.
location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" {
  add_header "" "";
}
location ~ "^/pagespeed_static/" { }
location ~ "^/ngx_pagespeed_beacon$ps_dollar" { }


## PageSpeed Admin paths
include apps/pagespeed/admin_ui.conf;

Could you add the following to your configuration?:

pagespeed MapOriginDomain http://ep.yimg.com https://mydomain.com/img ep.yimg.com;

That should set ngx_pagespeed up for correctly routing back any incoming requests resulting from the domain rewriting you have configured.
