I am needing to add HTTP headers to any URL request from a WebView.
I've got it working for direct URLs, but redirect URLs are being missed.
I've tried spawning a NSURLConnection and catching the redirected URL
there, and that works, but I can't seem to stop the original WebView
request, so I get multiple URL requests.
Here's the code I've tried:
-(NSURLRequest *)webView:(WebView *)sender resource:(id)identifier
willSendRequest:(NSURLRequest *)request redirectResponse:
(NSURLResponse *)redirectResponse fromDataSource:(WebDataSource
*)dataSource
{
// Update the status message
@try
{
if (redirectResponse)
{
NSMutableURLRequest *mrequest = [request mutableCopy];
myConnection = [[NSURLConnection alloc] initWithRequest:mrequest
delegate:self];
// attempt to cause this original request to be cancelled
//[[webView mainFrame] stopLoading]; // when uncommented, this
results in a crash
return mrequest;
} else
{
NSMutableURLRequest *mrequest = [request mutableCopy];
if (mrequest)
{
[mrequest retain];
[self AppendHeaders:mrequest];
return mrequest;
}
}
return request;
}
@catch (id exception)
{
return request;
}
return request;
}
- (NSURLRequest *)connection:(NSURLConnection *)connection
willSendRequest:(NSURLRequest *)redirectRequest
redirectResponse:(NSURLResponse *)redirectResponse
{
if (redirectRequest && redirectResponse) {
NSMutableURLRequest *mrequest = [redirectRequest mutableCopy];
if (mrequest)
{
[mrequest retain];
[self AppendHeaders:mrequest];
return mrequest;
}
}
return redirectRequest;
}
Using Charles, I can see the redirected URL being loaded. It loads 3
times with the code above, the first time with the correct headers.
I need it to just load once. Without the NSURLConnection
initWithRequest it loads once, but without the headers.
Any suggestions would be greatly appreciated.
