You might think what is the big deal if your Drupal site performs badly.To put it simply, if the performance of your site is poor,you will lose a lot of potential customers. So, one of the core aspects of a Drupal website is its performance. We had worked on a Drupal site that had several blocks. To enhance the site's performance, one of the steps we had taken was to set up a time base caching for all blocks. Are you curious to know how we did this? Read ahead.

The Drupal Block cache alter module helps to alter block caching. One important thing is that we can set time for cache. This is significant because caching time of blocks should depend on the context. Also, if a block needs to be refreshed while some contents are created, or if we need to cache blocks based on different situations, this module will be useful for you.

Steps for installing and enabling block cache alter module in drupal 6

However,simply enabling the module didnt give the options such as cache time. For this, we had to apply one of the core patches available with the module. To apply patch, copy the suitable patch file to the modules/block folder and run the command,

 patch -p0 < filename 

Then, go to block cache alter settings in admin/settings/blockcache_alter and enable check box core patch. image1.png. This will make more options in block caching, like cache lifetime and refreshing options. image2.png

If you are placing a block using module_invoke(), setting cache doesn't take effect, because block doesn't belong to any region. In this scenario, first you have to set the cache for the block, including cache life time and call the block using module_invoke() as follows.

//This block is created by views.
//So, in usual cases, module_invoke code looks like, $block = module_invoke('views', 'block', 'view', 'block_delta');
//But here, it goes like this.
$block = module_invoke('blockcache_alter', 'block', 'view', 'views,block_delta');
print $block['content'];

So simple. Hope this will help

How can I fix this? Thanks, Sean webmaster access_time 15 Jul 2020 - 04:56 In reply to Icon doesn&#039;t show by Sean (not verified) What do you see when you view the source? Search for stumblethis_button and you should be able to see the code for the image and the URL. Then you should be able to troubleshoot from there.

Most webmasters do not realize this, but a lot of the content on lot of websites can be accessed from multiple URLs. A simple example would be where www.example.com and example.com leads to the same page. This is a fatal mistake in Search Engine Optimization and search engines penalize you for duplicate content. The correct configuration would be where the above two urls will lead you to the same page but example.com will redirect you to www.example.com with a 301 (Moved permanently) status which will not result in search engines penalizing the page. It is very easy to configure 301 redirects using Apache .htaccess file and the process is the same for a Drupal installation also.

I'm trying to make example.com show as www.example.com, and I'm running into difficulties. I'm on Apache 2.0 and using the following lines in my httpd.conf file: RewriteEngine on RewriteCond %{HTTP_HOST} ^xxxxxxxxxx\.com$ [NC] RewriteRule ^(.*)$ http://www.xxxxxxxxxx.com/$1 [L,R=301] When I go to http://xxxxxxxxxx.com, I get http://www.xxxxxxxxxx.com (as expected). However, when I go to http://xxxxxxxxxx.com/node/1 (it's a Drupal site), I get a 404 thrown and the URL changes to xxxxxxxxxx.com/var/www/drupal/node/1. Same thing with www.xxxxxxxxxx.com/node/1. Any suggestions? I want to run without Drupal's .htaccess file (instead incorporating these calls into my httpd.conf file). webmaster access_time 15 Jul 2020 - 04:56 In reply to Rewrite including filesystem path by Anonymous (not verified) I think the problem is with the base path which results in the redirection to /var/www/ part. The best approach I would think is to start with drupal htaccess and then strip out parts and move to httpd SNVC (not verified) access_time 15 Jul 2020 - 04:56 This is definitely a good guide. Thanks for this. wellyson access_time 15 Jul 2020 - 04:56 This is really nice and helpful. Add new comment
