+Node.js middleware for serving a favicon.
+
+A favicon is a visual cue that client software, like browsers, use to identify
+a site. For an example and more information, please visit
+[the Wikipedia article on favicons](https://en.wikipedia.org/wiki/Favicon).
+
+Why use this module?
+
+  - User agents request `favicon.ico` frequently and indiscriminately, so you
+    may wish to exclude these requests from your logs by using this middleware
+    before your logger middleware.
+  - This module caches the icon in memory to improve performance by skipping
+    disk access.
+  - This module provides an `ETag` based on the contents of the icon, rather
+    than file system properties.
+  - This module will serve with the most compatible `Content-Type`.
+
+**Note** This module is exclusively for serving the "default, implicit favicon",
+which is `GET /favicon.ico`. For additional vendor-specific icons that require
+HTML markup, additional middleware is required to serve the relevant files, for
+example [serve-static](https://npmjs.org/package/serve-static).
+
+## Install
+
+```bash
+npm install serve-favicon
+```
+
+## API
+
+### favicon(path, options)
+
+Create new middleware to serve a favicon from the given `path` to a favicon file.
+`path` may also be a `Buffer` of the icon to serve.
+
+#### Options
+
+Serve favicon accepts these properties in the options object.
+
+##### maxAge
+
+The `cache-control` `max-age` directive in `ms`, defaulting to 1 year. This can
+also be a string accepted by the [ms](https://www.npmjs.org/package/ms#readme)
+module.
+
+## Examples
+
+Typically this middleware will come very early in your stack (maybe even first)
+to avoid processing any other middleware if we already know the request is for
+`/favicon.ico`.
+
+### express
+
+```javascript
+var express = require('express');
+var favicon = require('serve-favicon');
+
+var app = express();
+app.use(favicon(__dirname + '/public/favicon.ico'));
+
+// Add your routes here, etc.
+
+app.listen(3000);
+```
+
+### connect
+
+```javascript
+var connect = require('connect');
+var favicon = require('serve-favicon');
+
+var app = connect();
+app.use(favicon(__dirname + '/public/favicon.ico'));
+
+// Add your middleware here, etc.
+
+app.listen(3000);
+```
+
+### vanilla http server
+
+This middleware can be used anywhere, even outside express/connect. It takes
+`req`, `res`, and `callback`.
+
+```javascript
+var http = require('http');
+var favicon = require('serve-favicon');
+var finalhandler = require('finalhandler');
+
+var _favicon = favicon(__dirname + '/public/favicon.ico');
+
+var server = http.createServer(function onRequest(req, res) {
+  var done = finalhandler(req, res);
+
+  _favicon(req, res, function onNext(err) {
+    if (err) return done(err);
+
+    // continue to process the request here, etc.
+
+    res.statusCode = 404;
+    res.end('oops');
+  });
+});
+
+server.listen(3000);
+```

+Create simple ETags
+
+## Installation
+
+```sh
+$ npm install etag
+```
+
+## API
+
+```js
+var etag = require('etag')
+```
+
+### etag(entity, [options])
+
+Generate a strong ETag for the given entity. This should be the complete
+body of the entity. Strings, `Buffer`s, and `fs.Stats` are accepted. By
+default, a strong ETag is generated except for `fs.Stats`, which will
+generate a weak ETag (this can be overwritten by `options.weak`).
+
+```js
+res.setHeader('ETag', etag(body))
+```
+
+#### Options
+
+`etag` accepts these properties in the options object.
+
+##### weak
+
+Specifies if the generated ETag will include the weak validator mark (that
+is, the leading `W/`). The actual entity tag is the same. The default value
+is `false`, unless the `entity` is `fs.Stats`, in which case it is `true`.

+HTTP response freshness testing
+
+## Installation
+
+```
+$ npm install fresh
+```
+
+## API
+
+```js
+var fresh = require('fresh')
+```
+
+### fresh(req, res)
+
+ Check freshness of `req` and `res` headers.
+
+ When the cache is "fresh" __true__ is returned,
+ otherwise __false__ is returned to indicate that
+ the cache is now stale.
+
+## Example
+
+```js
+var req = { 'if-none-match': 'tobi' };
+var res = { 'etag': 'luna' };
+fresh(req, res);
+// => false
+
+var req = { 'if-none-match': 'tobi' };
+var res = { 'etag': 'tobi' };
+fresh(req, res);
+// => true

+- If a number is supplied to `ms`, a string with a unit is returned.
+- If a string that contains the number is supplied, it returns it as
+a number (e.g: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of

+# parseurl
+
+[![NPM version](https://badge.fury.io/js/parseurl.svg)](http://badge.fury.io/js/parseurl)
+[![Build Status](https://travis-ci.org/expressjs/parseurl.svg?branch=master)](https://travis-ci.org/expressjs/parseurl)
+[![Coverage Status](https://img.shields.io/coveralls/expressjs/parseurl.svg?branch=master)](https://coveralls.io/r/expressjs/parseurl)
+
+Parse a URL with memoization.
+
+## Install
+
+```bash
+$ npm install parseurl
+```
+
+## API
+
+```js
+var parseurl = require('parseurl')
+```
+
+### parseurl(req)
+
+Parse the URL of the given request object (looks at the `req.url` property)
+and return the result. The result is the same as `url.parse` in Node.js core.
+Calling this function multiple times on the same `req` where `req.url` does
+not change will return a cached parsed object, rather than parsing again.
+
+### parseurl.original(req)
+
+Parse the original URL of the given request object and return the result.
+This works by trying to parse `req.originalUrl` if it is a string, otherwise
+parses `req.url`. The result is the same as `url.parse` in Node.js core.
+Calling this function multiple times on the same `req` where `req.originalUrl`
+does not change will return a cached parsed object, rather than parsing again.
+
