Exclude caching cusotm module by Magento 2 built in Full page cache(FPC problem)

by

The question:

I am having a strange issue regarding built-in FPC in magento2.

I have a custom module, in its index controller, it just renders a phtml file. This phtml file shows some information retrieving it from a custom table. This is just a simple thing that I have done here.

The problem is when I disable FPC in magento 2 the contents are displayed correctly, but when I enable the FPC than it renders the blank page .

See below two screeshot for the scenario analysis.

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

You can disable block to cache by layout xml code.

See below example code for disable block from cache.

<block class="MagentoFrameworkViewElementTemplate" template="sample:module::sampletemplate.phtml" name="sampleblock" cacheable="false" />

cacheable=”false” is use for that. you can disable like this.

Method 2

From

cacheable=”false” will create uncacheable page, not just block.

For private content you should be using approach described in here:
