# Magic Parameters

Pimcore supports some *magic parameters* which can be added as parameter to every request.

### pimcore_nocache
Setting this parameter disables every kind of cache, eg.: `http://www.example.com/my/page?pimcore_nocache`  
This parameter only works if [`DEBUG MODE`](../18_Tools_and_Features/25_System_Settings.md) is on.

### pimcore_outputfilters_disabled
Disables all output filters, incl. the output-cache. But this doesn't disable the internal object cache, 
eg.: `http://www.example.com/my/page?pimcore_outputfilters_disabled=1`  
This parameter only works if [`DEBUG MODE`](../18_Tools_and_Features/25_System_Settings.md) is on.

### pimcore_log
Enables verbose logging (including database queries) to a separate log file only for this particular 
request called with this parameter, eg.: `http://www.example.com/my/page?pimcore_log=my-log-name` 

If no value is set to this parameter the log file can be found here: `/var/logs/request-[Y-m-d_H-i-s].log`. 
If a value is given, the value will be part of the log files name: `/var/logs/request-[NAME].log`
  
This parameter only works if [`DEBUG MODE`](../18_Tools_and_Features/25_System_Settings.md) is on. (this is also the successor of the parameter `pimcore_dbprofile` in earlier versions)

### pimcore_disable_host_redirect
Disables the "redirect to main domain" feature. This is especially useful when using Pimcore behind 
a reverse proxy. 

### pimcore_debug_translations

Configures the translator to return the given translation key instead of actually translating the message. This can be
useful to debug translations or to get an overview over used translation keys. Example: http://www.example.com/my/page?pimcore_debug_translations=1

This parameter is only available if activated via configuration and is enabled by default in the `dev` environment which
is by default automatically chosen when debug mode is active:

```yaml
pimcore:
    translations:
        debugging:
            enabled: true
            # you could also change the parameter from pimcore_debug_translations to something else
            parameter: my_custom_parameter
```
