Is there a filter for static file request?
Apr 14, 2017 03:24 AM|markblank05|LINK
is there a way to intercept or filter the request before serving the file? like if i request
so i can get the random.jpg the w and the h, then return it as an image
i tried intercepting it using MapRoute and it doesn't work when i use app.UseStaticFiles();

use action method for processing image.
url like: localhost:5000/controllName/ActionName?image=random.jpg&w=100&h=100

You can try this:
public void Configure(IApplicationBuilder app) { // ... var staticFileOptions = new StaticFileOptions { OnPrepareResponse = (context) => { var fn = context.File.Name.ToLowerInvariant(); if (fn == "random.jpg") { var width = context.Request.Query["w"]; var height = context.Request.Query["h"]; // Your logic here } else { // Some default logic for all other files context.Context.Response.Headers.Add("Cache-Control", "public, max-age=15552000"); // 180 days } } }; app.UseStaticFiles(staticFileOptions); // ... }
