PostData not being received over 3G but is over wifi.

[Tom Gallacher]

Hi,

I have implemented ASIFormDataRequest within my application and I am
able to post and receive the correct http response over WIFI on an
iPhone 3Gs. However when the iPhone is then set to not use the wifi no
PostData is received by the server, however I am still able read the
response.

It seems strange that this works over wifi but not 3G.

Thanks,

Tom Gallacher

The my current implementation is:

ASIFormDataRequest *httpRequest = [ASIFormDataRequest requestWithURL:
apiUrl];
[httpRequest setPostValue:@"iphone" forKey:@"Text"];
[httpRequest setPostValue:@"iphone" forKey:@"SourceDevice"];
[httpRequest setPostValue:@"true" forKey:@"Debug"];
[httpRequest setFile:outputFileURL forKey:@"video"];
[httpRequest setUploadProgressDelegate:progressIndicator];
[httpRequest setTimeOutSeconds:20];
[httpRequest setDelegate:self];
[httpRequest setDidFailSelector:@selector(uploadFailed:)];
[httpRequest setDidFinishSelector:@selector(uploadFinished:)];
[httpRequest startAsynchronous];

With the debug params on I get this:

Content-Disposition: form-data; name="Text"

Try doing [ASIHTTPRequest setShouldThrottleBandwidthForWWAN:YES] when
you try to upload data on the server over 3G.

This should solve your problem if there are no multiple requests going
on.

Anoop, is there an iOS or carrier limit on the number of active concurrent
requests when going over 3G or Edge?

After tcpdumping on my server I can see the only difference between
the two headers are that the Wifi connection has a cookie set. and the
3g connection has: Accept: */*.
Could it be the cookies not being handled correctly on 3G?

Just to clarfiy i have tried Anoop's code that was provided however It
hasn't worked. As far as i am aware I am only making one single
request.

It seems that it could be the mobile phone network I am on, It seems
that post data is sent but not interpreted by Apache on Vodafone Uk.
However the same build on the same iPhone model on O2 Uk seems to post
fine.

For me, I was trying to upload some data over 3G and simultaneous
requests for fetching data from server.

I was testing in United States and on At&T network. Bandwidth
throttling restricts number of bytes sent per second.

And that setting can be changed as per the requirement of network. I
am using default value in ASIHTTP.

Bandwidth throttling has is working fine for me. I am doing throttling
only when there is upload and not for other requests.

I am using my own Apache server where I am uploading data from mobile
phones.

Could you print what error message you are getting on server or
client ??
