Routing some URL to localhost in windows - windows

I want to pass some external URL to localhost with all their parameters (such as GET, POST, etc) while other URLs of these hosts be untouched.
for example:
example.com/path-to-file/server.php?params => localhost/server.php?params
But:
example.com/path-to-file/other.php?params => example.com/path-to-file/other.php?params (Direct routing)

Add your host entry in the following file:
%systemroot%\system32\drivers\etc\
Make sure you edit the file as administrator.
You could then start a simple web server listening to requests and pass them to the original url only if they contain the parameters (i.e. file name) you want.

Swagger page being redirected from https to http

AWS Elastic Load Balancer listening through HTTPS (443) using SSL and redirecting requests to EC2 instances through HTTP (80), with IIS hosting a .net webapi application, using swashbuckle to describe the API methods.
Home page of the API (https://example.com) has a link to Swagger documentation which can bee read as https://example.com/swagger/ui/index.html when you hove over on the link.
If I click on the link it redirects the request on the browser to http://example.com/swagger/ui/index.html which displays a Page Not Found error
but if I type directly in the browser URL https://example.com/swagger/ui/index.html then it loads Swagger page, but then, when expanding the methods an click on "Try it out", the Request URL starts with "http" again.
This configuration is only for Stage and Production environments. Lower environments don't use the load balancer and just use http.
Any ideas on how to stop https being redirected to http? And how make swagger to display Request URLs using https?
Thank you
EDIT:
I'm using a custom index.html file
Seems is a known issue for Swashbuckle. Quote:
"By default, the service root url is inferred from the request used to access the docs. However, there may be situations (e.g. proxy and load-balanced environments) where this does not resolve correctly. You can workaround this by providing your own code to determine the root URL."
What I did was provide the root url and/or scheme to use based on the environment
GlobalConfiguration.Configuration
.EnableSwagger(c =>
{
...
c.RootUrl(req => GetRootUrlFromAppConfig(req));
...
c.Schemes(GetEnvironmentScheme());
...
})
.EnableSwaggerUi(c =>
{
...
});
where
public static string[] GetEnvironmentScheme()
{
...
}
public static string GetRootUrlFromAppConfig(HttpRequestMessage request)
{
...
}
The way I would probably do it is having a main file, and generating during the build of your application a different swagger file based on the environnement parameters for schemes and hosts.
That way, you have to manage only one swagger file accross your environments, and you only have to manage a few extra environnement properties, host and schemes (if you don't already have them)
Since I don't know about swashbuckle, I cannot answer for sure at your first question (the redirect)

Host a static site from file system to an url via hosts file

I have this static site. When development, I am accessing it with the following url:
file:///C:/development/pokedex/index.html
But this static site works with angular, and when angular try to get any view via ajax, it fails becouse Cross origin requests are only supported for protocol schemes.
Now, I tried to modify the Hosts file to try to access it into localhost or any other url different than file:///etcetc, adding the following line to such file:
hosts:
file:///C:/development/pokedex pokedex
But when I attemp to access http://pokedex, nothing happends.
How can I debug my site without having to upload it to a server just to debug it?

ASP.NET Web API: How do you read server variables in a Web API controller?

How would you read the following server variables in an ASP.NET Web API controller?
HTTP_HOST
SERVER_NAME
REMOTE_HOST / REMOTE_ADDR
I see a System.Net.Http.HttpRequestMessage Request defined, but I don't see a collection containing these variables.
I'm running a website on a single IP with multiple host headers and I need to determine which site they used to get there.
EDIT:
It ended up being something like this:
((System.Web.HttpContextWrapper) Request.Properties["MS_HttpContext"])
.Request.ServerVariables["HTTP_HOST"]
The information you are looking for is dependent on the host you are using and Web API is designed to be host independent. So.... the information you are looking for will be buried in the httpRequestMessage.Properties collection and it will be different depending on your host.
If you move to using the Owin adapter then you will get a standardized Owin environment object.
I was able to all that information from the RequestUri within Request
Request.RequestUri.Scheme + Uri.SchemeDelimiter +
Request.RequestUri.Host + (Request.RequestUri.IsDefaultPort ? string.Empty : (string.Concat(":", Request.RequestUri.Port)))

Editing HOSTS file for specific URL?

I have tried to edit my HOSTS file to block just a specific url like so:
127.0.0.1 google.com/pagetoblock
127.0.0.1 www.google.com/pagetoblock
However that isn't working.
Does anyone know where I'm going wrong?
Your HOSTS file only allows you to set the IP address for (as the name suggests) the host (e.g. google.com or www.google.com). You cannot set the IP address for specific pages.
You could use a tool like Microsoft Fiddler to set the IP Address for specific URLs, but this would require Fiddler be running continuously.
Fiddler has a rules engine accessed by Rules → Customize Rules.
There is a great set of samples for your learning, but the following script should work.
For example, to block the logo on the http://www.google.co.uk homepage, you could use the following script:
if (oSession.url == "www.google.co.uk/images/srpr/logo3w.png"){
// Prevent this request from going through an upstream proxy
oSession.bypassGateway = true;
// Rewrite the IP address of target server
oSession["x-overrideHost"] = "127.0.0.1";
// Set the color of the request in RED in Fiddler, for easy tracing
oSession["ui-color"]="red"; 
}

How can I rewrite URLs in the Zeus web server for Mobile useragent?

I need to redirect anyone with a mobile user agent to a file called mobile.php.
My web hosting provider, Net Registry uses the Zeus web server.
Here's the script I've written from my research
RULE_1_START:
# get the document root
map path into SCRATCH:DOCROOT from /
match IN:User-Agent into $ with iPad|iPod|iPhone|Android|s+Mobile
if matched then
set OUT:Location = /mobile.php
endif
RULE_1_END:
I used the instructions on my host's site.
I pasted that into their console and it has worked to do redirects. Net registry have some odd console thing that you submit and it takes 10 minutes to update the zeus server config (annoying as hell).
Anyway my issue is that it redirects me to the wrong location:
So if you visit the site, with a user agent string that contains ipad|ipod|android|\s+mobile then you will trigger it ()
It takes me here:
http://example.com.au/mobile.php,%20catalog/index.php
I can't work out how to fix that, or why that happens because at the moment this file exists:
http://example.com.au/mobile.php
as does this one:
http://example.com.au/index.php. Contents of this file are:
<?php header("Location: catalog/index.php");
Any ideas on how I can make this work more like an apache .htaccess url Rewrite?
the official Zeus documentation
Fixed it by changing
set OUT:Location = /mobile.php
to
set URL = /mobile.php
From the manual...
Using Request Rewrite Scripts
To use the request rewriting functionality, create a script in the Zeus Request
Rewrite Scripting Language. The script contains instructions telling the
Virtual Server how to change the URL or headers of requests that match specified criteria.
The Virtual Server compiles the script, and (if the rewrite functionality is
enabled) uses it every time it receives a request. It runs the commands in the
script, changing the URL if it matches the specified criteria. Once the script is
finished, the Virtual Server continues processing the resulting URL.Zeus Web Server 4.3 User Guide
142 Configuring URL Handling
When changing the URL, the rewrite functionality can only change the local
part of it, that is, the part of the URL after the host name. For example, if a
user requests http://www.myhost.com/sales/uk.html, the rewrite
functionality can only make changes to /sales/uk.html. This means that
you cannot use the rewrite functionality to change the request to refer to a
file on another Virtual Server.
For example, the following script illustrates how to change requests for any
HTML files in the /sales directory so that the user receives them from the
/newsales directory instead:
match URL into $ with ^/sales/(.).html
if matched set URL=/newsales/$1.html
The rewrite functionality can also change the HTTP headers that were received
with a request, and create new HTTP headers to be returned to the user. For
example, the following script changes the HTTP host header, so that a request
for www.mysite.com/subserver is redirected to the Subserver
www.subserver.mysite.com:
match URL into $ with ^/([^/]+)/(.)$
if matched then
set IN:Host = www.$1.mysite.com
set URL = /$2
endif
