HttpWebRequest slow fix by setting Proxy to null

Question

I rectified my HttpWebRequest initial calls being slow by using the suggestion mentioned at

Why is this WebRequest code slow?

One of the suggestions mentioned to set the Proxy to null and things will speed up.

I have done this and it worked.

However Im concerned about the impact of this when I deploy this at some client sites....

It may be at some client sites that have configured their domain to go through a proxy to reach the server in which I am making my HttpWebRequest to.

Will setting Proxy properly to null impinge upon this?

Thanks

I wondered the same thing too. I was not able to find any answer to this question, though.

However, I did find that you can accomplish the same effect as hard coding httprequest.Proxy = null by adding a setting to the application config file:

<system.net>
  <defaultProxy>
    <proxy bypassonlocal="true" usesystemdefault="false" />
  </defaultProxy>
</system.net>

My thinking is that if I ever find myself at a customer site where I need to change the automatic proxy detection I can remove the settings from the config file.
