UBB.Developers Forums UBB.threads 7 Development How Do I? ISP caching problem

Hi,

Since the first affordable broadband has just been offered in Bangkok many of my members living here have moved to it. And that seems to be causing a bit of a problem as this ISP seems to cache pages.

This results in members often getting an old page (usually the main index) and it seems that they are logged in as somebody else. Hitting CTRL-F5 to force a refresh solves this, and they cannot actually get into any of the private areas of other members.

However, I have some hidden forums on my board and I would really prefer people without access not knowing about them. I use this ISP as well though and I can imagine it is possible that someone without access gets a copy of my main index page, and would then see these forums.

So, I am asking for suggestions on how to fix this. I thought of maybe adding the user's displayname or userid to the URL, but am open for other suggestions (nor do I know how to do that I have to admit).

Sanuk!

PS We are on 6.4.1 beta (hopefully moving to 6.5 soon)

Yeah, I wonder if that would do the trick. Append their username and/or usernumber to the URLs leading to the main index, and postlist.

Or even better - when generating the links - grab the unix timestamp, which would be a 10 digit number - changing every second, and append it as a variable to the URL. Then the URL would be different.

Assuming they only get served a cached page if the URL (and variables in it) is exactly the same, this would keep every URL unique (even for the same user - as cached pages for the same user can create read/unread issues).

Hi,

Thanks, that might be better.
Do you know where the URL is generated?

"Assuming they only get served a cached page if the URL (and variables in it) is exactly the same"

I think this is the case, because as soon as I move to another page (especially My Home) I do get the correct page.

Sanuk!

You shouldn't need to mess with your URL's like that.

In templates/ubbt_header.tmpl...

CHANGE THIS:

Ah ha! Good call Twisty!

Hi,

Thanks, implementing now

Sanuk!

could this be implemented to only one page, and not all the pages?

for example - just the "My Home" page? Many people upload avatars and then change them to something else a day later. After they change them, their old avatar had been cached (by god knows what???), but they seem to forget about hitting that [F5] REFRESH key and all they get is their previous graphic.

Am I way off on this suggestion - Am i running the only site here who has a few users with this problem?

I know what you're referring to, and I find it a tad annoying as well.

I'll tinker around to see if I can come up with anything

Ok here's the fix

That did the trick - it was exactly what I was looking for! Sneeky, but it works like a charm!!!

Thanks twisty!!
