ajax - jQuery.get() works on IE, but jQuery.post() does not -

i have strange problem. i'm making pretty standard ajax-call jquery, refuses work internet explorer 7.

the code following:

$.ajax({   url: updateurl,   cache: false,   type: 'post',   data: params,    success: function(data){     handleresponse(data);   }  }); 

the weird part that, if change type 'get' works correctly. have determined 'post' ie not send server @ all.

i'm setting kind of headers prevent caching, have no effect on 'post' problem.

just know, according docs $.post() (which shorthand ajax call):

pages fetched post never cached

try setting datatype returned data , add error handler alert errors:

$.ajax({   url: updateurl,   cache: false,   type: 'post',   data: params,    success: function(data){     handleresponse(data);   },   error: function(xhr,textstatus){     alert(textstatus);   }  }); 

also, sure page it's posting getting post variables , not variables?
