How to get wxCurl to automatically follow redirects?

I have a project that uses wxCurl to retrieve a file over HTTP. However, if the server sends a 301 or 302, all I get back is an empty string. I heard there was a way to get cURL to follow the location: headers sent by the server. How is this done?

Also, how do you set t开发者_如何学JAVAhe User-agent header in wxCurl?

Call mywxCurlHttpObject->SetOpt(CURLOPT_FOLLOWLOCATION, 1);

that will set the underlaying libCurl option correctly.

I don't know about the user agent -- you'd have to set that in the header in libCURL, but I don't see a way to set those with the wxCURL wrapper

When you call wxCurlHTTP::Get() wxCurl overrites all settings you've done so far in wxCurlBase::SetCurlHandleToDefaults()...

In wxCurlHTTP::Get() your can add the line SetOpt(CURLOPT_FOLLOWLOCATION, 1); after the method is calling SetCurlHandleToDefaults() or you just inherit the method in a new class and add it there.

I've tried it with my RSS import tool written in wxWidgets & wxCurl. It worked!
