Add http headers to Cassini via config

Question

Our asp.net web site is currently deployed to an IIS7 server. We are setting some http headers via the config file such as this:

<httpProtocol>
  <customHeaders>
    <remove name="X-UA-Compatible" />
    <add name="X-UA-Compatible" value="IE=EmulateIE7" />
  </customHeaders>
</httpProtocol>

This works great for myself as I host my personal web under IIS. My Co-Worker is pretty bent on continuing to use Cassini for his development experience, which means our custom headers are not being sent. Is there a way to tell cassini to send these headers?

I would rather not have to code up a custom module to add this, and I don't want to add the header on every page in our site.

Answer 1

Perhaps you could add a pre-compiler directive in the Global.asax so it will only add the header when compiled in DEBUG mode:

protected void Application_BeginRequest(object sender, EventArgs e)
{
#if DEBUG
    HttpContext.Current.Response.AddHeader("X-UA-Compatible", "IE=EmulateIE7");
#endif
}

The production RELEASE compilation would ignore this but continue to add the header via the web.config setting in IIS.

This feature is in the todo for the next release of CassiniDev, amongst others that may be of interest.
