Question

I’m trying to to send some post data to a Apache server from iPad application using the ASIHttp library.

actually I need to send huge data to the server and that means I need to compress the request body so I write some code to send the data and compress the request BUT there are no parameters received on the server !!!

the iOS code is :

        NSURL * URL = [NSURL URLWithString:myURL];  
        ASIFormDataRequest *ASIRequest = [ASIFormDataRequest requestWithURL:URL];
        ASIRequest.shouldCompressRequestBody=YES;
        ASIRequest setPostValue:data forKey:@"data"];
        [ASIRequest startSynchronous];
        NSError *error = [ASIRequest error];
        if (!error) {
            NSString *response = [ASIRequest responseString];
            NSLog(@"response %@" , response);
        }

PS: if I removed the ASIRequest.shouldCompressRequestBody=YES; everything works fine and I can see the data but when use it I see nothing on the server

1. the request can be seen on the server but with no parameter
2. noway to send such data over GET method.
3. the server configuration are fine.

any solution ? any comment or idea can help ?

Answer 1

By default, most web servers do not support compression on POSTs. The accepted answer here does a really good job explainining it: Why can't browser send gzip request?

According to official documentation, this feature has only been tested with Apache servers.

EDIT:

Here is a code snipt that compresses the actual post data:

if ([self shouldCompressRequestBody]) {
    NSError *err = nil;
    NSData *compressedBody = [ASIDataCompressor compressData:[self postBody] error:&err];
    if (err) {
        [self failWithError:err];
        return;
    }
    [self setCompressedPostBody:compressedBody];
    [self setPostLength:[[self compressedPostBody] length]];
}
