IE makes extra GET-request on hash change

Question

When I make an XMLHttpRequest, I also change window.location.hash.

For example, mysite.com/gallery/q#1 becomes mysite.com/gallery/q#2.

When this happens, IE8, as Fiddler and nginx logs show, makes this strange extra request to mysite.com/gallery/ (which is 404).

The page isn't reloading, it's like an XMLHttpRequest.

GET http://mysite.com/gallery/ HTTP/1.1
Accept: */*
Referer: http://mysite.com/gallery/q
User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727)
Accept-Encoding: gzip, deflate
Host: mysite.com
Connection: Keep-Alive

Separately, hash change or Ajax-request won't trigger this extra one.

Another thing to note – the extra request occurs not on every Ajax-request. It happens seemingly randomly.

Can it be nginx misconfiguration? Or is it simply one of the many IE8 bugs?

Is there a workaround? I don't want this extra load.

Update

Here's the Ajax code ($ stands for jQuery):

var id = link.getAttribute('data-id')

var xhr = $.ajax({
    cache: false,
    url: '/stock-items',
    method: 'GET',
    data: { id: id },
    dataType: 'json'
})
xhr.success(function (data) {
    if (currentId === id) {
        toggleLoader(false)
        displayData(data)
    }                                                                                                                           
})

And hash manipulating code:

function setHash(link) {
    var index = $(link).index()
    globals.location.hash = index + 1
}

Also tried with the hash-symbol with the same result:

globals.location.hash = '#' + index + 1

The Ajax-request is on click on gallery image links:

links.on('click', function (e) {
    setHash(this)                                                                                       
    loadData(this)
    e.preventDefault()
})

I also tried these links to have the href attribute set to #1, #2 and so on in the HTML (and removed e.preventDefault()). So that the hash changes naturally. Nope, the extra request is made anyway.

What's the exact JavaScript you're using to change the hash? — EricLaw, Jan 23 '12 at 20:57

Is the visitor being redirected to the affected page from another? If so, it's likely to be a known IE bug.

Take a look at this similar question: javascript location.hash refreshing in IE

Greg, yes, I've seen this question. It's not a redirect, and solutions provided in the answers to that question don't work for my case (I checked). – katspaugh Jan 23 '12 at 20:14
Is the site live now? Can you share the path to the affected page? – greg84 Jan 24 '12 at 11:17
Greg, it's not live yet. I can share the code, though. See the updated question soon. – katspaugh Jan 25 '12 at 00:18
