DAP works great with the WP Super Cache plugin. Probably works with others too – but we have officially tested it with just Super Cache at this time.
And this page below walks you through the full set up of the WP Super Cache plugin.
Go to Settings > WP Super Cache
You are now on the “Easy” tab. Don’t do anything here just yet.
Go to Advanced tab.
Be sure to put a “Check” (or “Select” the radio button) next to each of the following items
Cache hits to this website for quick access. (Recommended)
Use mod_rewrite to serve cache files. (Recommended)
Compress pages so they’re served more quickly to visitors. (Recommended)
Don’t cache pages for known users. (Recommended)
Don’t cache pages with GET parameters. (?x=y at the end of a url)
Cache rebuild. Serve a supercache file to anonymous users while a new file is being generated. (Recommended)
Clear all cache files when a post or page is published or updated.
Extra homepage checks. (Very occasionally stops homepage caching) (Recommended)
Only refresh current page when comments made.
List the newest cached pages on this page.
Click on Update Status button.
Keep scrolling down until you see the Accepted Filenames & Rejected URIs section.
You’ll see a big text area under the text “Add here strings (not a filename) that forces a page not to be cached”. +
There, add the following, one per line.
Obviously, your member content page URL’s may be slightly different. So make sure you customize it to suit your own URL’s.
Next to back to Easy tab at the top.
Now you select the “Caching On” option and save.
That’s it for the setup.
Now, on to testing.
If you organize all of your member content under a main parent page, say “members”, then all you need to exclude from caching, is /members/
For example, if your URLs include year and you don’t wish to cache last year posts, it’s enough to specify the year, i.e. /2004/. WP-Cache will search if that string is part of the URI and if so, it will not cache that page.
So basically, excluding just one single URL – /members/ – from caching, will make sure all of the following as well remain UN-CACHED.
You get the idea. When you exclude “/members/”, any URL that starts with that same text, will be excluded.
So here’s how you set up the “hierarchy” of the pages.
First, create the page “members“.
Then, when you create the “login” page, make sure you select the “parent” of the page, to be the “members” page.
So, instead of the login page URL looking like… http://YourSite.com/login/
… because the parent page is “members”, that also gets added to the URL, and the login page URL becomes like this:
If you created a page called “example” and made the “login” page as its parent, then the URL for this new page becomes:
So you see how that hierarchy works. Use that to arrange all of your member content under the main “ancestor”, which is “members”, here in our example.
But if you have already completed creation of all of your content, then you’re just going to have to do a little extra work to identify all of your pages and posts and exclude the member content from the list. DAP makes this a little bit easier as well.
If you log in via FTP and go to the “dap” folder, inside, you will see a file called “dap_permalink_dump.php”. If you download that file to your desktop, and open it with any text editor (Notepad, Dreamweaver, etc), inside you will see a full list of URL’s of all posts and pages from your WordPress site. You can just take that list, remove separator text like “Posts” and “Pages”, and trim the list of URL’s down to just your member content, you can take that and paste it right into the WP Super Cache > Advanced tab > Accepted Filenames & Rejected URIs section.
Now open multiple browsers – like Firefox, Chrome and Internet Explorer (or Safari). Use at least 3 separate browsers.
Next, go to your login page in one of them, and then log in. Then go to same login page in another browser – make sure it doesn’t say “You are already logged in”. It should show you the DAP login form. Same on third browser.
Next go to the profile page while logged in as member. Do the same in other two browsers, while logging in as three different people. Each profile page should you show you different information.
If you crated 3 separate products, with 3 different users, then logging in as those 3 different users on the 3 different browsers, should show you 3 different sets of pages.
All this is just to make sure there’s no caching going on of your membership content, that’s all.
If all of this works, then you’re all set with caching for your non-membership content, and no caching for your dynamic member content.
If you want to speed up your web site, you must address the core issue, which is — your web site is getting more traffic than your web server (web hosting account) can handle.
So here are a few ways in which you can speed up your web site:
If you’re having weird issues – like members logging in and seeing other people’s profile information, or logging in as a valid user and being told “Sorry, you don’t have access to this content” – then it’s probably because of a “cache” plugin.
Do not use cache plugins on your membership site
DAP now fully works with WP Super Cache (and possibly other cache plugins too).
You just need to make sure that you exclude your member content (including the login page) from being cached.
Follow the steps below to clean up some the junk left behind by cache plugins (regardless of whether you see them in your plugins section, and regardless of whether they are currently active).
1) You wish to disable your cache plugin that is currently enabled
2) You previously had one enabled at some point in the past
3) You don’t believe you ever had a cache plugin enabled in the past
4) You were redirected to this page by the DAP support team because of potential caching-related issues
Now re-test whatever the issue was before, and it would have probably been resolved now.
That should do it.
If the issue still persists, let us know via a support ticket.
A: If all files are stored right on your web site, and you have a large amount of video, audio and other files, then a lot of people viewing and downloading them from your site will use up a lot of resources on your server – like site loading time, server memory, server bandwidth, etc – and your site could slow down considerably. Plus, on top of that, there are also bandwidth charges that your host will charge you with for all of those downloads, which are usually not very cheap.
And don’t put too much faith in your web host’s “Unlimited Bandwidth” clause, because if you read the fine-print carefully, you’ll see that as per their TOS, if you consume large amounts of bandwidth and use too much of the server resources, this could cause other web sites (belonging to others) on the same server to slow down and have a degrade in performance, especially if you are on a shared hosting account. And they could consider this abuse of their TOS, and could either slap you with huge bandwidth or server utilization fees, or may even ask you to take your web site elsewhere because you’re causing issues for other site owners on the same server.
Instead, if the files are stored on Amazon S3, then you don’t have to worry about your site slowing down, or you using up too much bandwidth and getting slapped with huge bandwidth fees, because the files are being served from Amazon’s huge S3 servers which have tons more resources and speed compared to your web host.
Plus in the long run, bandwidth is cheaper on S3 compared to your web host.
A: Not directly, not by itself. By default, DAP can only protect files (and any other content) that is on the same web site where DAP is also installed. For large files, we do recommend that you store files on a fast, scalable file server like Amazon S3. Now, the page or post itself (in which you post that Amazon S3 link) can be protected by DAP, and no un-authorized user can even see the content of the page (or the link within that page).
However, once a user has authorized access to a page because they’re a member, now they can see the page where you have that Amazon S3 link.
It’s similar to posting a public YouTube video on a protected DAP page on your web site. Sure, DAP can protect the page from un-authorized users, but authorized users can actually see the page, and see that it’s a YouTube video, and clicking on that video will directly take them to a page on YouTube.com, which DAP has no control over, and cannot protect once they leave your web site.
Similarly, DAP cannot directly protect that external link to your file stored on Amazon S3. And that’s where our Amazon S3 plugin S3MediaVault.com (S3MV) comes into the picture.
S3MV can make sure that your files on Amazon S3 cannot be accessed directly by anyone, even if the link were shared with others via email or on a forum, and can ONLY be accessed through a page or post on your web site (web site where you have installed the S3MV WordPress plugin).
NOTE: The S3MV plugin is included for free with your purchase of any DAP license, starting with the Unlimited-site license and above.
A: S3MediaVault is not a “true streaming” solution. Which means, it doesn’t stream videos in real time, but rather, plays the video by buffering the file as the viewer is watching the video. And that’s the right way to do it, if you care about your viewers.
This means your viewers will be able to rewind, even put the video on pause (especially for large videos), so that it keeps buffering in the background, and then come back and watch it later when it has fully “loaded” , so that they won’t experience any real-time buffering. This is very useful for viewers that don’t have fast internet connections.
What this also means, is that anyone who watches your video, can also use free, browser plugins (like DownloadHelper) that allow you to download a video that you’re watching in your browser. This is not a security breach. They are able to download it to their computer, only because they currently already have been given authorized access to the video/audio itself.
Please remember that anything that is accessible online – like audio, or video – can always be easily downloaded to the viewer’s desktop. There are many different ways in which you can download what you are viewing in your browser. The bottom-line is this: If a video or audio is able to be viewed in a browser, it can easily be downloaded – or “recorded” using screen-capture solutions like Camtasia, or audio capturing solutions like Audacity), and then saved – to the viewer’s computer.
S3MediaVault makes sure no one can directly access your files from your S3 account, and can only play or view it from your site (where the S3MediaVault plugin is installed).
Then combine that with the Page/Post protection of DigitalAccessPass (DAP),which can make sure only certain people (like paid members, or free but registered users) can access the post or page where the S3MediaVault embed code is published.
Combine DAP + S3MediaVault, and you would have now completely locked down your content from any and every kind of un-authorized and illegal access.
So once someone has paid for your content (or registered for it), and are authorized users who have a right to view or hear that content, it’s OK that they get to download what they’re eligible for, to their computer, for offline use (like during their morning walk, or on the treadmill, or in their car, or when standing in line at the theme park!)
We don’t believe it is a good idea for you to completely prevent even your legitimate, paying members from downloading your videos. After all, they’ve paid for it, and should be able to download it and watch it offline (like on their mobile device, ipad, iphone, etc).
In fact, the best membership sites that we’ve seen, and have helped set up, offer the content in multiple ways: Download the videos for playback later universally on all devices (mp4), download audio version of this video (mp3), download the transcript of the video (PDF), etc.
The more you make it easier for your members to consume your content, the more they will love being a member, and stay with you longer.
If you absolutely must have “streaming” videos that viewers cannot download at all (and also cannot easily buffer ahead and play at their own convenience), then we recommend Vimeo.com/pro.
