C＃.net System.Net.WebClient ..服务器端还是没有？

Question

I have a C#.net webform that does a simple response.write in content type JSON format. It works greats from every client I test it with - including a TinyWebDB API call from an Android phone.. but don't worry about that API for this question.

I added some serverside code to that web form to read and scrape a web page as follows.

System.Net.WebClient myWebClient = new System.Net.WebClient();
Stream myStream = myWebClient.OpenRead(what);
StreamReader sr = new StreamReader(myStream);
string s = sr.ReadToEnd();

I'm under the impression that code is all Server Side!?

I tested the page from IE, FF and Chrome.. all work great. However If I attempt to call the web form page from TinyWebDB the call works great and I get data back, but I get a 404 error on the server side read of the webpage??

It's almost as if System.Net.WebClient requires something from or is doing something on client itself. i thought the reading of the page was all happening serverside and behind the scenes on my serer. Why would my serverside code care about what browser or API initiated the call to the webform?

Should I be using another class?

Many Thanks.

Answer 1

That is serverside code.

Where does the variable "what" get set? Is the form TinyWebDB client munging your form input values?

Is it possible that the site you are requesting is rejecting your request because you're hitting it too fast and you've just been unlucky with it being that client every time?
