Set up an HTTP proxy to insert a header

Question

I need to test some HTTP interaction with a client I d rather not modify  What I need to test is the behavior of the server when the client s requests include a certain  static header   I m thinking the easiest way to run this test is to set up an HTTP proxy that inserts the header on every request  What would be the simplest way to set this up

If you have ruby on your system  how about a small Ruby Proxy using Sinatra  make sure to install the Sinatra Gem    This should be easier than setting up apache   The code can be found here

Rather than using a proxy  I m using the Firefox plugin  Modify Headers  to insert headers  in my case  to fake a login using the Single Sign On so I can test as different people

I have had co-workers that have used Burp   an interactive HTTP S proxy server for attacking and testing web applications   for this   You also may be able to use Fiddler   a HTTP Debugging Proxy

You can also install Fiddler  http   www fiddler2 com fiddler2   which is very easy to install  easier than Apache for example    After launching it  it will register itself as system proxy  Then open the  Rules  menu  and choose  Customize Rules     to open a JScript file which allow you to customize requests   To add a custom header  just add a line in the OnBeforeRequest function   oSession oRequest headers Add  MyHeader    MyValue

I do something like this in my development environment by configuring Apache on port 80 as a proxy for my application server on port 8080  with the following Apache config   NameVirtualHost    lt VirtualHost   gt      lt Proxy http   127 0 0 1 8080   gt        Allow from all     lt  Proxy gt      lt LocationMatch   myapp  gt        ProxyPass http   127 0 0 1 8080 myapp       ProxyPassReverse http   127 0 0 1 8080 myapp       Header add myheader  myvalue        RequestHeader set myheader  myvalue         lt  LocationMatch gt   lt  VirtualHost gt    See LocationMatch and RequestHeader documentation   This adds the header myheader  myvalue to requests going to the application server
