What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 131 Stack Exchange communities.

Certain items on Stack Overflow pages take forever to load (on the order of minutes) when accessed via a proxy server. This includes MathJax and syntax-highlighted code, but also the "add comment" and "edit" links (e.g. on this page). The rest of the page is displayed immediately.

Is there anything someone can do to fix this?

I first noticed this with MathOverflow's MathJax-rendered Latex; and found it reported and discussed here:

Not quite sure what you mean -- Stack Overflow doesn't even use MathJax. –  balpha Jul 6 '11 at 14:15
    
Are you sure you're on the right site? The Maths SE Site is math.stackexchange. –  tombull89 Jul 6 '11 at 14:16
    
Did you arrive at this site by typing meta.stackexchange.com into your browser? That site has been decommissioned, and its URL now redirects to this site, meta.stackoverflow.com. Unfortunately, this site no longer supports questions about SE 1.0, so the Meta MO post is probably the end of the line. –  Pops Jul 6 '11 at 14:18
    
I arrived at this page via google, looking for the right place to ask stackexchange support questions. I had assumed mathoverflow was a stackexchange site, and the end of the discussion in the link seemed to suggest it was a stackexchange problem, not a MathJax problem. –  Dan Jul 6 '11 at 14:26
    
Sorry if I ended up in the wrong place. However, having said that, this page here also displays the slow loading problem -- it is just less noticeable because it's only the "add comment" and "edit" links which do not work until the throbber finally stops spinning (status bar message "Waiting for meta.stackoverflow.com..."). –  Dan Jul 6 '11 at 14:28
    
Which browser are you using? (This should probably be asked on the Math-Meta site, but the mods will most like move it for you). –  M. Tibbits Jul 6 '11 at 17:21
    
Firefox 5 on Linux. I believe it is a proxy issue because the problem does not arise when bypassing the proxy. –  Dan Jul 6 '11 at 17:51

I think your browser is probably choking on the MathJax on the Mathematics website. This occurs for me in Cross-validated from time to time -- especially if I load the page and then click on to another stack-exchange site before [cv] has finished loading.

The source in questions for the 'add comment' and 'edit' links is easily examined -> Firefox has a 'view selection source' which I think chrome has too? not sure? Anyways, the source is:

<div class="post-menu"><a href="/q/97613/152009" title="short permalink to this question" id="link-post-97613">link</a><span class="lsep">|</span><a href="/posts/97613/edit" title="edit this post">edit</a><span class="lsep">|</span><a id="flag-post-97613" title="flag this post for serious problems or moderator attention">flag</a></div>

As this is quite standard html, I doubt your browser is choking on it. It could be a serving issue -- I know nothing of the backend implementation, but again, I doubt these links are the issue. It's probably Mathjax.

Note I posted the source for the 'link|edit|delete|flag' block, but the html input for the 'Add Comment' is very similar. –  M. Tibbits Jul 6 '11 at 17:24
    
I really doubt it is MathJax. Consider that MathJax works fine on non-stackexchange sites (see also the discussion I linked to in the question), and that the same problem arises on pages like this one that have no MathJax content. It's just that if parts of the page are not displayed, it is visually more apparent that the page has not finished loading. –  Dan Jul 6 '11 at 17:45

Regarding the 'add comment'/'link' code, again (like you) I doubt the code itself is responsible. It is more likely that the (js parts of the?) webpage itself is not responsive until it has completely finished loading. –  Dan Jul 6 '11 at 17:47
    
This is where I will step aside and say I'm not a web developer. I just see firefox's multiple requests to stop a javascript parse which hasn't completed and I've, perhaps incorrectly, attributed this to MathJax. –  M. Tibbits Jul 6 '11 at 17:48
