VB6 HTTP Server — Now with Route Parameters & Path Segments

[woeoio]

I've been building an HTTP server in VB6 and just added two features that make it feel a lot more like a modern web framework:

? Parameter Routes ({param})
Define dynamic URL segments just like Laravel, Express, or Flask:

' Register routes with parameters
Router.Add "/api/user/{id}", "UserController@Show", OnlyGet
Router.Add "/api/user/{userId}/post/{postId}", "PostController@Show", OnlyGet
Router.Add "/api/group/{groupId}/user/{userId}", "GroupCtrl@Detail", OnlyGet
Retrieve them in your controller via RouteParams:

Public Sub Show(ctx As cHttpServerContext)
    Dim id As String
    id = ctx.Request.RouteParams("id")   ' e.g. "123"
    ctx.Response.Json Array("userId" & id)
End Sub

Matching rules:

Fixed segments match exactly (case-insensitive)

• {name} matches any non-empty segment
• Segment count must match
• Exact routes are matched first (O(1) dict lookup), then parameter routes are tried

? PathInfoList — Quick Access to URL Segments
Every request now has a PathInfoList collection that splits the URL path into indexed, keyed segments:

' Request: GET /api/user/list?page=1

ctx.Request.PathInfoList(1)          ' ? "api"
ctx.Request.PathInfoList(2)          ' ? "user"
ctx.Request.PathInfoList(3)          ' ? "list"
ctx.Request.PathInfoList.Count       ' ? 3

' Check if a segment exists
If ctx.Request.PathInfoList.Exists("api") Then ...

' Iterate all segments
Dim i As Long
For i = 1 To ctx.Request.PathInfoList.Count
    Debug.Print ctx.Request.PathInfoList(i)
Next i
Full RESTful Example
' Routes
Router.Reg "Product", New cProductController
Router.Add "/products", "Product@List", OnlyGet
Router.Add "/products/{id}", "Product@Detail", OnlyGet
Router.Add "/products/{id}/reviews", "Product@Reviews", OnlyGet
Router.Add "/products", "Product@Create", OnlyPost
Router.Add "/products/{id}", "Product@Update", OnlyPut
Router.Add "/products/{id}", "Product@Delete", OnlyDelete

' Controller
Public Sub Detail(ctx As cHttpServerContext)
    Dim id As String
    id = ctx.Request.RouteParams("id")
    ' ... fetch from DB ...
    ctx.Response.Json product
End Sub

What's New in Code
File Change
cHttpServerRouteItem.cls NEW — Parses {param} patterns, matches paths, extracts params
cHttpServerRouter.cls Updated matching: exact match first, then parameter route traversal
cHttpServerRequest.cls Added RouteParams (Dictionary) and PathInfoList (cCollection)
100% backward compatible — existing exact-match routes work exactly as before.

Oh, okay. This is a very good note. Then I will take the time to sort out a more complete work introduction and post it to codebank. Thank you very much
