Just found an interesting issue:

    r.Static("/assets/", p.rootFolder+"/assets")
    r.GET("/:code", p.redirectHandler)

Generates:

panic: wildcard route ':code' conflicts with existing children in path '/:code'

Seems like it's due to the fact that Static uses *filename wildcard. My plane is due in soon, so can't dig into it now, but I think any static wildcards should be generated below the url path specified, not within root domain.

As in:
/assets/*filename
instead of 
/*filename

Any thoughts?
