XmlDataSource & Website Proxy

[sck10]

Hello,

How do you set the website proxy using the XmlDataSource control?

Thanks, sck10

Hello Steve,

As for the XmlDataSource control, it doesn't expose a property for us to
configure webproxy to access external web resource. Actually, the
XmlDataSource control is designed for accessing local file document or
string based Xml content mostly. For your scenario, if your XMLDataSource
want to retrieve XML Data from an external site that need to be resolved
through a proxy, you can consider the following options:

1. Since by default the XMLDatasource control will use the system proxy
setting (within the machine level .net framework system.net configuration),
we can override it in our web application's web.config file. For example:

=================================
<system.net>
<defaultProxy >
<proxy
proxyaddress="http://jpnproxy:80"
bypassonlocal="True"
/>

</defaultProxy>
</system.net>
=======================

or if you do not want to make this setting affect all pages in the
application(only for individual pages or a sub directory), you can use the
<locationelement to scope the setting:

=============
<location path="XML/RSSDataSource.aspx">
<system.net>
<defaultProxy >
<proxy
proxyaddress="http://jpnproxy:80"
bypassonlocal="True"
/>

</defaultProxy>
</system.net>
</location>
=====================
2. You can also programmtically use WebRequest component(which can accept a
explicit webproxy setting) to retrieve the XML content and then assign it
to the XmlDataSource.Data property programmtically. e.g.

================
protected void Page_Load(object sender, EventArgs e)
{

//use webrequest to get the XML
string xml = GetXMLFromRemoteUrl(...);

XmlDataSource1.Data = xml;
}
================

Hope this helps. If there is any other questions, please feel free to let
me know.

Sincerely,
