hello,
any more information anywhere about options or how this can help?

currently running nginx x-accel and memcached but im wondering if this can help speed up image serving somehow.

thank you

 

[TickTackk]

Currently when serving the attachments, XenForo will add Expires: Thu, 19 Nov 1981 08:52:00 GMT and Cache-control: private, no-cache, max-age=0.

This add-on allows you to change the Cache-control: private, no-cache, max-age=0 to Cache-control: private, max-age=[days selected in in ACP options] or Cache-control: public, max-age=[days selected in in ACP options] depending on what suits your needs and Expires: [request time] + [days selected in ACP options].

The result being loading a thread or any page with large amount of image attachments being very fast as the images will be cached.

(Or at least that is how I expect it to work )

It's exactly how it works. For some of the really heavy image threads at our photography forum the load time for visitors revisiting a page have been dramatically reduced. Sites using a CDN wouldn't be affected but for anybody who (a) allows guests to view attachments [we only allow image attachments so it's not an issue for us] and (b) is serving the attachments from their local server and (c) the size of the attachments can be pretty big then this really helps page load times when revisiting a thread.

Public or Private?? Guests Vs Members I'm guessing?

 

[Seeker-Smith]

PHP 7.4.9 I don't see any difference in load times.

Nope. This should explain more on the difference between public vs. private.

PHP 7.4.9 I don't see any difference in load times.

Are those images viewable by guests?

 

[Seeker-Smith]

Nope. This should explain more on the difference between public vs. private.

Thanks. I now get public private. The images I want to cache are not viewable by the public just members.

I just want to confirm. I'm using cloudflare to hide my ip. Should I use private or public if I only allow members to view attachments? Private?

 

[TickTackk]

Just use whatever you would use if you didn't want to hide your IP.

 

[gogo]

Just use whatever you would use if you didn't want to hide your IP.

I do want to hide my IP. That's one of the reasons I use cloudflare..

 

[TickTackk]

As I said, use whatever you would use if you didn't have to hide your IP because your IP is not being "leaked" via this add-on.

 

[MattW]

I've got this installed, but I'm not seeing the headers being changed for attachments

 

[TickTackk]

Is the attachment viewable by guest?

Is the attachment viewable by guest?

No, guests can't view attachments on my forum.

[TickTackk]

No, guests can't view attachments on my forum.

That should be fixed now.

Hello;

the images are open to guests on my forum, should the plugin settings be like this? How do I check that this plugin is working correctly?

I have the same settings as you because attachments are viewable by guests on my forum too. I have no idea if it's working as intended though.

 

[TickTackk]

You will need to check the cache-control header of the image attachments and see if they are being updated as expected.

should the plugin settings be like this?

If you are still wondering about public vs. private, please read here and if you still do not understand a thing, go with the default (public).
