uploading xml string

Edit: I want to know suppose if there's another way to upload the xml content without passing it as a POST parameter. is this possible?

I currently have a client app that manipulates an xml file, then wants to upload its content back to the server, If I uploaded back as a get/post strin开发者_C百科g in an ajax call, is there a limitation as to how big the string is? is there other way?

The limits on get/post string length are both theoretical and vary between browsers and servers.

For sending a large chunk of data though, like an xml file, or for sending any data that would result in a change in stored data on the server you should use a post request. You shouldn't have to worry about the size limit of the post string unless you know your server is configured to allow ridiculously small amounts of post data or that your xml file is heinously, unimaginably large.
