i have post request:

$.post( this.loggerUrl, {url:this.url, action:action, timestamp:date.getTime()} )

where this.url == document.location

$.post -> $.ajax ->

s = jQuery.extend(true, s, jQuery.extend(true, {}, jQuery.ajaxSettings, s));

and inside jQuery.extend we have line 604:

else if ( copy !== undefined)

target[ name ] = copy;

in this line we have redirect, when target == location and name == "href".

in my own script i'm fix it by replacing

$.post( this.loggerUrl, {url:this.url, action:action, timestamp:date.getTime()} )

to

$.post( this.loggerUrl, {url:this.url.toString(), action:action, timestamp:date.getTime()} )

but how about other users?

i spent one hour before found this feature -)

(sorry for my english)
