LSCache + ESI + Smarty

[serpent_driver]

Hi all,

I am looking for a documentation about how ESI can be used with Smarty. ESI works, but only if I set a hardcoded file path for src. If I set a Smarty tag for src I get error:

[an error occurred while processing this directive]

Is there any log file for debugging this error?

Hi ,

Could you provide example code you used? How can we reproduce it?
Just to clarify it is on WordPress application?

Best

This one works

<esi:include src="/hardcoded_file_path/file.php" cache-control="no-cache" />

This one doesn't

<esi:include src="{$box_shopping_cart}" cache-control="no-cache" />

It is no Wordpress application. WP doesn't use Smarty.....!

Hi @serpent_driver ,

yeah, I was thinking if you were asking about smarty cache or php engine.

Unfortunately I don't think LiteSpeed ESI support smarty syntax. But it support cache-control= "public" and cache-control= "private" as well for different scenario you need.

Best,
Eric

I have to correct myself. Using this Smarty tag is wrong. When I debug this tag there is no source, it displays the content of an array, so I have to search for other places.

There are some news and now I know why it doesn't work. ESI processor tries to fetch the URI in <esi:include src=""> like a regular request, but if there is a Smarty tag, ESI doesn't know what to do with Smarty tag. That means there is no way to use Smarty tags with ESI src attribute.

Instead of <esi:include> I also tried <esi:inline>. If <esi:inline> is defined the content within ESI will be displayed, but only if ESI support is disabled or not defined in LS Cache rules. If ESI support is ON, LS removes the complete code fragment. It doesn't matter what attributes are used in this ESI tag, whenever there is <esi:inline> defined LS removes it from source code.

Meanwhile I know how Smarty works with ESI.
