making another http request when the first one is done iOS

I want to do the following: I am making an ASIFormDataRequest and I want when it is finished, invoke a new one:

So my code will look something like this:

 ASIFormDataRequest *request=[ASIFormDataRequest requestWithURL:url];
    [request setDelegate:self];
    [request setPostValue:mail forKey:@"email"];
    [request setPostValue:cod forKey:@"code"];
    [request setPostValue:tab forKey:@"table"];
    [request setPostValue:name forKey:@"name"];
    [request startAsynchronous];

- (void)requestFinished:(ASIHTTPRequest *)request
{
   //request 1 is done, invoke request 2
 ASIFormDataRequest *request_2=[ASIFormDataRequest requestWithURL:url];
    [request_2 setDelegate:self];
    [request_2 setPostValue:other_data forKey:@"info"];
    [request_2 setPostValue:phone forKey:@"phone"];
    [request startAsynchronous];
}

and I do not know what I must place in requestFinished so as to identify which of the 2 requests has finished? or if there is another way for doing so?

You could just invoke different methods when the different requests are finished.

ASIFormDataRequest *request=[ASIFormDataRequest requestWithURL:url];
[request setDelegate:self];
[request setDidFinishSelector:@selector(firstRequestFinished:)];

- (void)firstRequestFinished:(ASIHTTPRequest *)request
{
   //request 1 is done, invoke request 2
    ASIFormDataRequest *request_2=[ASIFormDataRequest requestWithURL:url];
    [request_2 setDelegate:self];
    // Work with your request, and then
    [request setDidFinishSelector:@selector(secondRequestFinished:)];
    [request startAsynchronous];
}

- (void)secondRequestFinished:(ASIHTTPRequest *)request
{
   //request 2 is done, invoke request 3
    ASIFormDataRequest *request_3=[ASIFormDataRequest requestWithURL:url];
    [request_3 setDelegate:self];
    // Work with your request, and then
    [request setDidFinishSelector:@selector(thirdRequestFinished:)];
    [request startAsynchronous];
}

- (void)thirdRequestFinished:(ASIHTTPRequest *)request
{
   // Do whatever should be done now.
}

Since your requests are executed sequentially, it would suffice to maintain an integer instance variable/property which is set to zero when you start the first request, and incremented in requestFinished.

ADDED: There is also an error in your code: In requestFinished you should start the new request with [request_2 startAsynchronous];, instead of re-starting the previous request.

ASIFormDataRequest extends ASIHTTPRequest class and it has "tag" property as NSInteger type.

You can set different tags your requests and when you recieved a response you can check what is the tag of that request.

That makes you identify which one it is.

If the seconde request dont use the result of the first one, you can put all requests on a queue: 

[self setNetworkQueue:[ASINetworkQueue queue]];
[[self networkQueue] setDelegate:self];
[[self networkQueue] setRequestDidFinishSelector:@selector(requestInQeuFinished:)];
[[self networkQueue] setRequestDidFailSelector:@selector(requestFailed:)];
[[self networkQueue] setQueueDidFinishSelector:@selector(queueFinished:)];

for (NSString *tmpDic in array) 
{
    ASIHTTPRequest *link= [ASIHTTPRequest requestWithURL:[NSURL URLWithString:@"link"]];
    [[self networkQueue] addOperation:request];
}

[[self networkQueue] go];

in addition to Martin R responece, you can use [[self networkQueue] requestsCount] to get the REST of requests number in requestInQeuFinished:.
