* Hello, i have created a page:
* site.loc/page/
* this page is cached correctly, but if i use query string for example
* site.log/page?letter=A then cache won’t work
* I enabled “query string cache” but it won’t work for pages
Can you please check?
* More info:
Query string on pages are used for custom templates, for example
movies list. ?letter=A will show the movie list filtered by letter a, it would
be cool if cache worked also for this pages.

* Hello, sorry but i don’t have a live website yet,
i was developing a solution
for my client and i noticed this problem.
* I have something similar to this:
[https://codepen.io/the_ruther4d/post/custom-query-string-vars-in-wordpress](https://codepen.io/the_ruther4d/post/custom-query-string-vars-in-wordpress)
* You can replicate the problem creating a page template (page-{ID}.php), then
use this function inside:
* ```
if (get_query_var('test')) {
echo "test ok";
} else {
echo "query not set";
}
```
* if you call the page with “site.loc/page?test=value” then it wont be cached.

* Sorry but i don’t have any ETA for going online with this website.
Try to create
a page on your local wordpress
* Inside theme directory put a file page-**PAGE_ID**.php where “PAGE_ID” is the
id of the page you created.
* Content of page-PAGE_ID.php
* ```
Query not set
```
* functions.php
* ```
function add_custom_query_vars( $qvars ) {
$qvars[] = 'letter';
$qvars[] = 'test';
return $qvars;
}
add_filter( 'query_vars', 'add_custom_query_vars' );
```
* Now in browser call url:
* `website.loc/?pagename=contacts&test=3`
* on the page u can see:
`WP Fastest Cache file was created in 0.2534019947052
seconds, on 25-02-20 19:14:39` but every time you refresh, the date changes and
no cache is created.
