Hello,

I would like to build a custom form and handle the POST data on a wordpress page. This works okay with add_filter to create dynamic content.

Litespeed shows strange behavior though when calling the page in the form action field – the resulting page will not be served form cache nor will css minimize jump in.

I separated the problem to a difference between GET and POST. When I redirect to a page with GET, the cache will work. If I use POST, the cache is missed.

https://yoonde.de/test/

Example page shows GET and POST button. Please open inspector to follow network traffic and see the difference.

Any help appreciated.
Regards Chris

The page I need help with: [log in to see the link]

Hi,

LiteSpeed Cache only caches “GET” , it won’t cache “POST”

Hello qtwrk,
I would understand, that it won’t be cached for privacy reasons, but minify/combining of css/js files is also not working on the POST request. Why is that?

Hi qtwrk,

here is the part from debug.log
I guess what you mean is “X Cache_control off – not GET method:POST”.
Not caching POST data is ok, but why is optimization skipped?
Thank you for your help.

Regards, Chris

Hi,

From the log
```
05/27/20 06:29:16.680 [109.91.32.181:60812 1 QjW] [Core] CHK html bypass: not get method POST
05/27/20 06:29:16.680 [109.91.32.181:60812 1 QjW] [Media] bypass: Not frontend HTML type
05/27/20 06:29:16.680 [109.91.32.181:60812 1 QjW] GUI bypassed by no counter
05/27/20 06:29:16.680 [109.91.32.181:60812 1 QjW] [Optm] bypass: Not frontend HTML type
```
the first line
```
		if ( $_SERVER[ 'REQUEST_METHOD' ] !== 'GET' ) {
			Debug2::debug2( '[Core] CHK html bypass: not get method ' . $_SERVER[ 'REQUEST_METHOD' ] );
			return;
		}
```
it just bypasses POST at all , so following
```
		if ( ! $is_html ) {
			Debug2::debug( '[Core] Footer check failed: ' . ob_get_level() . '-' . substr( $buffer, 0, 100 ) );
			return;
		}

		Debug2::debug( '[Core] Footer check passed' );

		if ( ! defined( 'LITESPEED_IS_HTML' ) ) {
			define( 'LITESPEED_IS_HTML', true );
		}
```
is_html will be false , and define( 'LITESPEED_IS_HTML', true ); won’t happen , so it doesn’t optimize.

It seems LSCWP was not designed to check POST output at all.

Maybe you could try define( 'LITESPEED_IS_HTML', true ); on your POST to force LSCWP does optimize.
