An easy way to get data across domains by Ajax __ajax

The restrictions on cross-domain communication are on the browser side, which is the client, so you can make a fuss from server-side code. This is the same as the last few days gzip, the problem is very similar to the gzip stream on the server because the ISA blocked to download compressed files, and finally wrote a compression agent placed on the server, forcing the return of compressed data.

The easiest way to do this is to write an agent to forward the data from another domain to the domain, and then use JS to access the agent.

such as code: Obj.sendrequest ("http://www.abc.com/test.aspx?p1=tt&p2=sss");

will become Obj.sendrequest ("redirect.aspx?url=http%3a%5c%5cwww.abc.com%5ctest.aspx%3fp1%3dtt%26p2%3dsss

Where redirect.aspx is forwarding agent, considering that some parameters of obj object may be post, should be on this proxy page server side to pass all request parameters to the requesting page, the following example omits this step. The code for the forwarding agent for ASPX is simple system..net.webclient wb = new System.Net.WebClient ();
byte [] b = wb. Downloaddata (request["URL"]);
Response.BinaryWrite (b);

This is actually more convenient than the server side is using XMLHHTP.
