TYPO3 - Deactivating cHash in own extension - 8LTS - typo3

Question

I'm trying to deactivate cHash in my extension ... the link for the show action looks like this:
/?tx_abc_abc[record]=1&tx_abc_abc[action]=show&tx_abc_abc[controller]=Abc&cHash=10c78febea3ae5dsdf535fb36ca6d08
In ext_localconf.php I tried to deactivate cHash like this:
ext_localconf.php
<?php
if (!defined('TYPO3_MODE')) {
die('Access denied.');
}
\TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin(
'Vendor.' . $_EXTKEY,
'Abc',
array(
'Abc' => 'list,show',
),
// non-cacheable actions
array(
'Abc' => 'list,show',
)
);
$GLOBALS['TYPO3_CONF_VARS']['FE']['cacheHash']['excludedParameters'][] = 'tx_abc_abc[record],tx_abc_abc[action],tx_abc_abc[controller]';
It's not working though. What am I missing?

Answer 1

You need to deactivate the cHash when building the links in your template. If you are using the ViewHelper <f:link.action>, then you need to set the attribute noCacheHash="1".

Answer 2

For TYPO3 9 and 10
All we need to do is configure the parameter from which you don't want
your chash to be calculated
For example, your link is like this
<f:link.action action="detail"
additionalParams="{
tx_plugin_action:{
param1:1, param2:2, param3: 3
},
param4: 4
}">Link Text</f:link.action>
Then you have to exclude all the parameters in Localconfiguration.php
'FE' => [
'cacheHash' => [
'excludedParameters' => [
'tx_plugin_action[param1]',
'tx_plugin_action[param2]',
'tx_plugin_action[param3]',
'param4',
],
],
]
Additionally: Remember that if any of the parameter is not
included here then it will calculate and generate chash
Note: Here We don't need to set noCacheHash="1" explicitely in viewhelper
