Proxies don’t preemptively copy content, they only store data that you’ve used.

Ok, thx

but,

into Nexus3 I configure the access at all public repo of Nexus2 like that :  
name : VersNexus2Public  
format : maven2  
Type : proxy  
URL : [https://nexus3.xxx:10443/repository/VersNexus2Public/](https://nexus3.xxx:10443/repository/VersNexus2Public/)  
Online : checked

```
Version policy : Release
Layouit policy : permissive
Content Disposirion : Inline

Remote Storage :
https://nexus2.YYY:10130/nexus/content/repositories/my-repo-public
Auto-block : checked

Strict Content Type Validation
checked

HTTP:
Authentification Type : Username
Username : admin
Password : xxxxxxxx

```

When I browse it, its status is : “Online - Ready to Connect”

After reading on internet, it’s because I don’t download anything. Ok.  
But how can I download something of Nexus2 from Nexus3 ?  
I need to download with cUrl, but I don’t find how to do it.

Thx

The Nexus GUI allows you to copy the base URL of the repository, i.e. [http://localhost:8081/repository/maven-central](http://localhost:8081/repository/maven-central) but you’d need to figure out the relative paths of content you have stored in Nexus 2
