Blog - Index

Matched /blog/{action=Index} - a default-valued route parameter.

action: Index
came from: the template default (URL omitted the segment)

Defaults vs. optionals

{action=Index} is omittable like {action?}, but the parameter never binds null - the missing segment binds "Index". URL generation mirrors this: ResolveUrl and the source-generated BrouterRoutes.BlogByAction() emit the default when you don't pass a value, so generated URLs always round-trip. A parameter can't be optional and defaulted ({id=5?} throws at parse time, framework parity).

@* /blog         → action = "Index" (the default)
   /blog/archive → action = "archive"
   Typed default: {id:int=5} binds int 5, not the string "5". *@
