Ext.Ajax.request, how can i disable timeout?

[eliotik]

I've looked for solution on forum, but all what i found is some replies for extjs 3.x.
i have tried to override Ext.data.Connection function request by setting

      request = {
        id: ++Ext.data.Connection.requestId,
        xhr: xhr,
        headers: headers,
        options: options,
        async: async,
        timeout: 0 // modified
      }; 

but no result, in firebug i saw that after create request object with timeout = 0, property request.timeout get random value(150, 1001, 289 and e.t.).
i need to do ajax request with no timeout, but i can not find the way how to.
can anyone help me please?
specs: ff8, extjs 4.0.2

You need to set it as an actual value as it is used in a setTimeout so just set it to a very high number... remember, it's in milliseconds.
