Cache Plugin Setup

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
Caching

Cache hits to this website for quick access. (Recommended)
Use mod_rewrite to serve cache files. (Recommended)

Miscellaneous

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)

Advanced    

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.
/dap/
/dap/.*\.php
/dap/admin/
/dap/admin/.*\.php
/login/
/members/
/my-profile/
/my-content/

 

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.

Content Organization Tips

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.

/members/login/
/members/home/
/members/my-content/
/members/my-profile/
/members/my-affiliate-info/
/members/course-1/
/members/course-1/module-1/
/members/course-1/module2/
/members/course-2/module-1/
/members/course-2/module2/

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:

http://YourSite.com/members/login/

If you created a page called “example” and made the “login” page as its parent, then the URL for this new page becomes:

http://YourSite.com/members/login/example/

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.

Getting A Full List Of Pages & Posts

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.

Testing Caching Impact

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.
