Consider enhancing ResourceUrlProvider to be able to change the domain, port, or scheme [SPR-12130]

[spring-projects-issues]

Brian Clozel opened SPR-12130 and commented

Now that the new
resource handling feature is in release candidate phase, we received feedback on several aspects.

One of those feedbacks is about changing the HTTP domain that serves resources. Here are some use cases for this:

• use of a 3rd party CDN on a separate domain (like Amazon cloudfront)
• use of a separate, cookie-less domain for better web performance, since sending cookies with each request can be a performance issue

See this Twitter conversation (in french) for reference.

We considered allowing ResourceResolvers to return complete URLs (and not only the resource path), but the current design for the Resource (Resolver/Transformer) chain is simple and cohesive -- focused mainly on the resource path. The ability to modify the domain, port, and scheme is a separate concern.

This issue is to explore the following solution:

• configuring globally an HTTP domain for all resolved resources though ResourceUrlProvider, making it a cross-cutting concern for ResourceResolvers
• this configuration could be done at the java config level with WebMvcConfigurerAdapter or WebMvcConfigurationSupport

Hi Guillaume DROUET, I think this issue might interest you as well.
Does your project need to change URL domains as part of the resolvers/transformer? Or a separate setting, as suggested here is acceptable?

Thanks,

Hi!

Of course! As mentionned in your twitter conversation, serving statics from a cookie less domain is important and in my project I take care of it by allowing to set several locations to use when writing URLs. So if spring allows to do it, the users may have the choice to choose between spring and third party framework as it can be done with PathResourceResolver and VersionStrategy. Sounds good to me if we can configure everything from WebMvcConfigurerAdapter...

It's resolved as duplicate of #16488 - and you've commented there as well.
