Re: [support] Drupal 7 and Page Caching

Great reply Mukesh, thanks. Varnish is definitely what we'll start with and see how that works. It looks like you need to use the Expire module in order to clear the cache on page update, correct? Also, I assume Varnish is very lightweight? So if we have a situation whereby we have another web app on the domain that doesn't require Varnish (e.g. example.com/webapp) passing that through Varnish and not caching would add virtually no overhead to the request? > Date: Mon, 9 Jan 2012 23:42:43 +0530 > From: Mukesh Agarwal <mukesh.agarwal17(a)gmail.com> > Subject: Re: [support] Drupal 7 and Page Caching > To: support(a)drupal.org > Message-ID: > <CAE55W0vykf2wXvVBaxuuTc3DsmjP_E=iMaPyZwLv7NUFn7S-_A(a)mail.gmail.com> > Content-Type: text/plain; charset="iso-8859-1" > > A small overview of the optimization techniques that we are talking about: > > 1.

Integrating a large, given Database into Drupal
by Bastiaan Zapf 11 Jan '12

11 Jan '12

Hello, I'm new on this list. I've got a question about Drupal. There is a large, existing database of documents (about 300.000 right at the moment, but other databases of comparable dimension might be added). This database is to be "integrated" into drupal somehow, so that Users could comment on documents, add new ones, rate them etc. The database contains not only document data, but also a wealth of metadata (hierarchical and causal relations, timestamps, versioning, authorship information, several distinct categories of documents - and some more). While this all sounds a lot like Drupal nodes already, i fear that just converting every document to a node would lose some of the metainformation and possibly break some features of drupal due to sheer number of documents. Would it be possible to have Drupal access that database directly instead of "nodes"? That way we'd probably save a lot of hassle. Would that be possible using a module? Any help appreciated, Basti

http redirection problem
by Amit Sethi 10 Jan '12

10 Jan '12

Hi all, I am quite new to apache php drupal stack. We are using drupal for an internal cms and for some needs we installed protect-node module. I tried installation on my local machine and the protect node module works fine . On our server some how the module does not work. I am accessing the installation as localhost/drupal on my local machine and as drupal.truzzers.com on the server , Now I am fairly sure this problem is because of apache config issue. Please do tell me how i can debug this -- A-M-I-T S|S

Drupal 7 and Page Caching
by DTH 09 Jan '12

09 Jan '12

I'm currently setting up my first big Drupal site that requires caching. The vast majority of the traffic is anonymous, so we can cache full pages. Currently, for a somewhat smaller site on D6, we use Boost, which works pretty well. The only other requirements are: ideally have relatively smart expiration of caches (as well as clearing cache on page updates, things like updating related views on node updates) and it definitely needs to work with Domain Access (shouldn't be a problem I don't think for most caching solutions?). Also, caching that can also works for logged in users would be a bonus, but unnecessary. (ie. it would be nice if things were quicker for admin users, but that's lower down the scale of things) What's the easiest/safest/most foolproof/most common way to cache things on Drupal 7? Drupal 7's native cache - stores it in the database? Would ideally want to avoid the database entirely. Boost - seems to have slowed down a lot on development for D7? Varnish - have never used but this seems the most common D7 way - anything to be aware of? If Varnish listens on port 80, and I also have non-Drupal pages on the same domain, how do you pass through things so people can access example.com/nondrupal/page? Do I need a reverse proxy or will Varnish pass it through itself? If starting from scratch, which version of Varnish should I use? Memcached - presumably am fine to use this alongside Varnish/Boost for logged in users. Do I just drop it in and use it for all systems (caching, sessions, locking)?

updating a drupal site
by Dick Hoogendijk 09 Jan '12

09 Jan '12

If I install the FreeBSD port of drupal all my files are owned by the user the webserver is running under (www). This way Drupal is very capable of updating/installing new core and/or modules. My question is: is it save(!) to have the files owned by *the user under which your Apache server executes? *

this code wrecks my site
by Marty Landman 09 Jan '12

09 Jan '12

I've set up a content type containing a single additional field, an existing field called field_associated_node which is a node reference. In my content type this associated node field may repeat an arbitrary number of times. Then I use the code below to get all these nodes and display them from an image cache file path. <?php $image = '<div class="image-gallery--image-link"><a href="/files/imagecache/lesson_image-fullsize/pictures/%s" ' . 'rel="lightbox[wall]"><img src="/files/imagecache/lesson_image-centercolumn/pictures/%s" /></a></div>'; foreach ($node->field_associated_node as $associated) { $assoc_node = node_load($associated[nid]); $file_path = $assoc_node->field_image_file_path[0]['value']; $bfr = sprintf($image, $file_path, $file_path); print $bfr; } ?> This works on my staging site, but on the live site as soon as I create one of these content type nodes the site's theme breaks. Restoring the database fixes it. I am wondering if my retrieval loop above is the problem, or where to look. This is a 6.22 site and the live site is in better shape than staging - other than this particular problem. Our plan was to wrap up a little more development and then migrate live down to staging for some maintenance; then this came up. :-( Marty

Title Across Blocks
by Swapnil Bhartiya 09 Jan '12

09 Jan '12

Hi, I am running Drupal 7. I want to be able to flow the title in the content page to go across the page. So that the right blocks come below the title, like this site: http://www.theverge.com/2012/1/7/2690375/corning-gorilla-glass-2-thinness You can see the title is above the right site block. How to do that? Best Swapnil
