Modify Request Header

[Dave Slinn]

I have a VB app hosting the Webbrowser control. I would like to add
"something" to the requests that app is submitted to our web application to
indicate that its from this webbrowser and not a separate instance of IE.

Is this possible, keeping in mind that I cannot add anything to the
registry, since a user may still use IE to visit the web app.

Dave,

It is different for the axWebBrowser 1.x than for the WebBrowser 2.0.
Basicly it is setting using the interface the designmode to on and off.

This for the webbrowser 2.0

DirectCast(WebB rowser1.Documen t.DomDocument,
mshtml.IHTMLDoc ument2).designM ode = "On"

Be aware that it has some strange side effects.

I hope this helps,

Cor

Hi Dave,

Welcome to MSDN newsgroup.
As for the modifying request header question you mentioned, based on my
research, the IE WebBrowser control's Navigate2 method can help specify our
custom http headers when we want to navigate to a certain web document. e.g:

private void btnNavigate_Cli ck(object sender, System.EventArg s e)
{
object obj = null;
object url = txtUrl.Text;
object headers = "aaa:aaavalue\r \nbbb:bbbvalue" ;//"Accept-Language:
en-us,zh-cn,fr-FR,de-DE;q=0.5";

axWB.Navigate2( ref url, ref obj, ref obj, ref obj,ref headers);
}
Also, the IWebBrowser control also has the "BeforeNavigate 2" event which
fires before navigate to a certain document, however, based on my testing,
we could only get the custom headers we specify in Navigate2 method there,
we can not reassign or modify the headers there. Regarding on this event,
I'll do some further research to see whether it is the by design behavior
or anything else to workaround it. (I test use the activeX control rather
than the .net 2.0's managed webbrowser control....)

I'll update you when I get some further information...

Thanks,

Hey Dave,

I've got confirmed with our IE guys about the IE WebBrowser control's
BeforeNavigatio n2 event, the Headers parameter in this event is actually
marked as [in] parameter from COM perspective, so this is read only .... So
far we're limited to use the Navigate or Navigate2 method to make http
request with our custom configured http headers....

Thanks,

Steven,

In my idea is it possible to reach the headers as I wrote, although not with
MSHTML because they are located outside the DOM area.

Not checked.

Cor

[Cor Ligthert [MVP]]

doh,

I thought that I had done something like this somewhere.

I copied the document as a textfile and than I could write it to disk
withouth that confirmation that is needed with the normal exec. I think that
you can use this as well to change the header.

However it is a while ago that I did this.

Cor

[Steven Cheng[MSFT]]

Thanks for your input Cor,

Yes, I admit that webbrowser control or MSHTML interface is not the proper
one to do http message customzing, I'd rather prefer the HttpWebRequest.
However, it seems that user interactive is the most important part in
Dave's scenario.....
