[TYPO3-english] Cache HTML comments

Fri Dec 21 10:35:07 CET 2012

Hello,

I've made an extension called "tinysource". It strips comments, tabs and  
stuff like that. I'm using the contentPostProc-all system hook.

When I now output $GLOBALS['TSFE']->content, I see such comments:

<!--INT_SCRIPT.639b280561f1a48a4a2733186f8f5e4b-->

<!--HD_ae90dcf1569a9e4b18c3406d256da3fc-->
<!--TDS_ae90dcf1569a9e4b18c3406d256da3fc-->
<!--FD_ae90dcf1569a9e4b18c3406d256da3fc-->

Okay, sure the first one is a non-cached plugin - but what does HD, TDS  
and FD stand for?
The HD comment is directly before closing </head> tag, TDS after <body>  
and FD before closing </body> tag.

TYPO3 strips these comments by itself when outputting the page. Are there  
any other such comments which are existing but in my case just not  
displayed?

Thanks in advance! :)

Greetings
Armin
