Shame on me, but i have a plain asp iis6 server and they want an ajax upload input with percent upload feedback, what should i do? do i ask for .net capabilities? any guidelines or some advice? Thanks for advance
I think you'll need a flash/silverlight component to do this, like Uploadify. I think there's also a way to do it without Flash using an iFrame hack or something, but I've never gotten that to work right.

Anyone know how I can check to see if a RTMP stream is online or not?
Streams are like rtmp://ip/user/stream, "user" being the different streams.
Any advise on how to do this?
Thanks!
I doubt there's a way of doing this just using HTML. You can use rtmpdump if you want to get a little technical:

Oh wow this is old.
Fixed this many moons ago using AS3 on the server side to request from the web server with variables to tell the database if the stream is active or not.
I am having a problem here. I am totally new to this concept of servers and web services and being able to get data uploaded and retrieved on different devices, but I want to learn it, say if I want to create an app like Instagram.
But that is EXACTLY what I dont want, a link to a long tutorial on the internet on how to create the most complex app ever, I want to start slow. After doing extensive power searches on Amazon there are basically no books that will help me. So I want to start slow, here is my goal:
Get a great understanding of how web service backends and servers work and be able to apply it in other app ideas I have and want to start developing
I would like to start by being able to create an app that allows a user to enter some text into a field, it uploads to the server, another device can press a button to retrieve the text and display it in a text view.
I do not know php, and every single tutorial I have entered on this website is literal mindeff, the reason for this is because everyone has a different solution, sync web service backend with Core Data, MySQL, parse, Rails and it truly overwhelms me because I do not know which one to pick! And even worse some people provide code but I have no understanding whatsoever, and its like looking at a totally new language!
I am not asking for code, in fact that is the exact opposite. I am asking for someone to really lay out their knowledge, how does it all work? What is the best tool? Some resources and links. Nothing too complex...
I hope you can truly understand my extreme confusion and frustration. I think the reason might be is I might not be ready yet for all this, but I want to push forward and carry out my app idea!
Thank you...
Update:
I have finally decided on a web service I would like to use, it is the Amazon S3 web service, I am still not fully comprehending the full process though, any help or ideas!?
Since you wanted to create an Instagram-type app, look at this: http://www.raywenderlich.com/13511/how-to-create-an-app-like-instagram-with-a-web-service-backend-part-12
This is a good link to servers: http://www.youtube.com/playlist?list=PLC71D7CFB6AF935E6&feature=plcp. Watch the list to get an understanding of servers.
Maybe you want to read up on sql. Understanding sql will help.. Again: http://www.youtube.com/course?list=EC32BC9C878BA72085&feature=plcp. Watch the list to get an understanding of sql...
I can pass you the link and you got to do the work....
Hope this helps...
Im trying to make a upload progress meter that works on ALL modern browsers in all operative systems (hence that I don't want to use SWFUpload, since all the demo pages fail in my computer, since I use Ubuntu).
Could someone give me please a hint where to look? I've googled the internet up and down without a solution...
Im running a server with PHP, but APC didnt work, apparently doesnt play nice with lightppd. Also I don't know Perl, so I'd rather not having to learn it for this.
I did this using ASP.NET not long ago. Basically, there's no pure HTML way to do it. What needs to be done, is to make changes on your server (in ASP.NET, I wrote an HttpModule to cache the current status of the upload - for PHP, Ruby, etc, there's likely similar methods to plug into).
Then on the client side - when a file was being uploaded, I made periodic ajax calls to the server to access the upload data that the server was caching. Then, using javascript, I would update whatever HTML progress bar.
You can see plUpload : http://www.plupload.com/
If you're using AJAX, you could go with this solution. And here are a few using jQuery.
So I am working on an iPad app that needs to talk to our company server to pull in some XML. In a browser, when the user tries to first navigate to the site, they are redirected to an SSO form that generates a cookie that is saved.
Now my application may need to replicate this behavior and generate the cookie so we can pull xml data off various parts of the site. I have never done anything like this before and there is very little documentation on the web so I am really looking for some general guidance. So far I have tried doing something like this, here.
That works to return the web form, but where to go from there eludes me. Does anyone have any ideas they would like to throw out? Essentially all that I need to do right now is authenticate the user's credentials, and save that verification. If there is an easier way to do that based on this template, I would definitely be open to suggestions. Any help at all would be greatly appreciated.
What i use for a lot of my networking is ASIHTTPRequest it is an API that is available, instead of trying to use low level sockets or the Apple APIs, with a decent guide and an active Google Group for questions. It can certainly handle xml requests as well as authentication. Here is a link to the site, ASIHTTPRequest
I am only just starting out with iPhone application development and have been doing some research with regards at getting data into an app using information available via the web.
I understand that I can access web pages using the NSURL* classes. Does anyone know how I might request data from a page that requires user input?
I can understand accessing an actual page, but I am not sure if (or how) I might be able to initiate the request and get the appropriate data back into my app.
Any help / pointers is very much appreciated.
EDIT_001:
I was thinking that I would have to interact with the actual controls on the page, but after a little more investigation I have found that I can simply use the request HTML that the page generates.

This question is really too broad ("how does http networking work"), and if you look around this site you will probably find several questions that will take you in the right direction. As a first stop, check out the ASIHTTPRequest framework. Many people use it, and it makes http networking really simple.
