Conflict With “Cache” Related Plugins

Well that sucks because my website without cacheing loads like moloassis and all the members are complaining! Is there another solution? Some sort of superpowered hosting? I’ve found that with the W3 Total Cache plugin and CDN, there has been a noticeable improvement in the site’s load speed.

Does this apply to CDNs? Content delivery networks? We have that on my site for faster delivery of photos. Please let me know if that is an issue.

Thanks,
Lia

Yes, this applies to CDNs as well.

Cache plugins have become an important part of running a WordPress site as php memory limits are now more easily hit. I’m sure you guys understand this far better than I, but I have run into that problem and have used a cache plugin to fix it.

So, if DAP can’t actually function when a cache plugin is installed (which seems to be required), my idea is this:

DAP can not be used on a public facing website that has lots of plugins activated (for drawing traffic, SEO features and social interactivity), hence DAP may better be placed on a separate site installation solely focused on the membership back-end of the public facing larger scale site.

Thus having 2 sites: DAP Membership site and WordPress public SEO site with all the plugin bells and whistles including cache plugin.

Thoughts?

Are there any plans to create a cache module specifically for DAP? Our site is quite slow, and we had to purchase a virtual private server from dreamhost to handle the additional load times on the pages.

Being able to cache things would be so great!

[…] a cache plugin has its place, but it’s certainly not for a membership site, where DAP will need to make calls to the database to figure out who’s viewing the content, […]

The are caching options available, some work, most don’t.

For example, w3 Total Cache for WordPress, you can enable some, but not all and it really depends on your setup. I enable the browser caching (except html) and minify features so that content is gzip’d and optimized at the data transmission level.

Then there’s Cloudflare. Depending on your content, your delivery styles etc., some caching will work you just have to put in the time to work out which.

– Is possible with wp-super cache to select what pages and URLs should be cached;
– Clear all cache files when a post or page is published;
– Dont cache pages for known users;
– Only refresh current page when comments made;

The problem with page cache and not caching for known-users is if you don’t have DAP sync’ing with WordPress, WP won’t know if the user is known or not.

Basically, all page caching is practically impossible.

You could however give CloudFlare a shot. I use it on all my sites. CDNs theoretically wouldn’t be a problem either since that’s not caching, but rather optimized content delivery.

Gav, I think that’s a brilliant idea and would love others to weigh in too.

I think that might just solve a few problems I’ve been having! Thank you.

Have 2x wordpress sites is 2x the work. The benefit gained from some of the caching in my opinion isn’t worth it.

You can use different types of caching and services with DAP.

My opinion on this article is that it’s similar to “electronic devices on aircraft must be switched off for take-off and landing”.

Why? Even ones without radios? Because it’s the only way to support such a measure. All or nothing, so DAP says “nothing” because to support everyone’s individual configuration is impossible for them, of course.

Try out different caching approaches and see what works, and what doesn’t. You’ll be surprised at what will work…

Also, get better hosting – such as cloud hosting that you can scale with your site. Feel free to ask me any questions about that if you’re considering it.

Cheers,
Paul.

Gav, good idea!
We need to test if this works.

@Gav, Lia, Deivid

Fortunately I started with this set up without even realizing that caching may be an issue with membership sites 🙂

So I have one “master” site where I have installed DAP and rest of the sites are just the front end where people click on the buy buttons. They get redirected to the DAP site as soon as they make payment. It works beautifully for me.

You can do whatever you want with these front end sites (install caching plugin etc.)

Now since only paying members know about my “master” site, there isn’t much load on it and I need not worry about caching.

Thank you @AJ!
This is good.

I was able to make WP Super Cache work by going to the “Advanced” settings tab, and adding file-name restrictions for any page that uses membership functions. In my case, everything that has ‘members’ in the path is excluded. That did the trick for me, but will require that you have some structure conventions for what part of your site is under membership control.

I’m not using the protected posts feature. So far, it looks like DAP functions with my W3 Total cache plugin.

Hi, I did not install any cache plugs, But while I’m adding content- my site getting more and more slow.

My question is: how you guys read this article and what do you think about changing .htaccess file? Will this be OK with DAP installation ?

Check your host. I was having a lot of problems when I was on dreamhost – almost unusable. Since switching to media temple Dedicated Virtual server, things have been much better.

Check out my site running on media temple with dap: http://www.pencilkings.com – nice and fast.

Cheers,

Mitch

AJ, simple but brilliant idea! the two separate sites would be easy for me because i’m just running an online exam simulator behind the DAP wall. i have a VPS so running two sites won’t be a problem. thanks again for a great solution!

I’m thinking about Cloudflare – can that be customized to not cache membership sections of my website?
Anyone have experience with DAP and Cloudflare?

Mitch – great site – are you still happy with media temple server?

@Ken – CloudFlare is awesome. It doesn’t cache pages, it’s primarily a CDN that caches static assets and distributes them across all its server locations. SO no worries about using it with DAP.

Anyway, my site uses nginx as a front-end proxy server and that caches css/js/images. Then I have W3 Total Cache doing compression and minification and Apache’s Mod Pagespeed crunching assets on the server.

So you definitely can use caching with membership sites. Every time I log into my DAP admin and see the “KACHING”: GOOD “CACHING”: BAD message I roll my eyes :/

Thanks for your response Anthony – I have changed my host to synthesis – they have CDN included- seems to be working great.
