LaTeX Fix Latex Editing Bug in PF Posts

AI Thread Summary
The discussion highlights persistent issues with LaTeX rendering in forum posts, where edits often do not display correctly in standard view. Users report that deleting one LaTeX formula can adversely affect subsequent formulas. The problem has been ongoing since April 2010, with no changes made to the server at that time, suggesting a potential caching issue introduced by the service provider. Users have noted that the problem occurs across all browsers and operating systems, indicating a widespread issue rather than a localized one. The common workaround involves refreshing and resending after each preview. There is a call for someone to address the bug in the editor, and questions are raised about whether server configurations could prevent caching of images. Additionally, there is confusion about how a transparent proxy determines which cached image to use, as users experienced inconsistent image displays during previews.

When I edit the latex in a post, the changes frequently do not appear correctly in the standard view. Deleting a latex formula when another one follows in the same post also has a strange effect.

Maybe someone could fix the bug in the editor.

There's probably 20 threads about this already, but most of them just say that the workaround is to refresh and resend after each preview. It appears that we've had this problem since April 13, 2010. According to our LaTeX guy, chroot, nothing changed on the server around that time. The problem is essentially the same in all versions of all browsers, on all operating systems. This strongly suggests that the service provider started doing some weird caching around then. Has anyone been in contact with them? Maybe Greg just needs to ask them to configure an exception.

I don't know this web stuff well enough to know if something can be done on the server. Is it possible to configure the web server software to instruct proxies to not cache images?

It seems to me that something else must be wrong, in addition to the fact that somebody is caching something. How does a transparent proxy know what image to use from the cache? Isn't the image identified by a file name or something? When I previewed these four LaTeX images, I got the two images from my previous post instead of 1 and 2, but 3 and 4 were fine.

Can someone explain how that's possible?
