Looking to send compressed content back to browsers I found this article ( http://betterexplained.com/articles/how-to-optimize-your-site-with-gzip-compression/ ) which I intend to try via .htaccess

This will still compress already cached content.

I was wondering if it has been explored already (or maybe exists already) to compress the cached content and serve that in combination with server settings ? It would save CPU/Memory resources as the cached content would not need to be compressed again and again.

If explored or existing, kindly point me in the right direction.

Did you made measurements and determined, that the problem is, undeed, in lack of compression?

I'm not dealing with a problem as far as I can tell !!?
I'm asking if it has been investigated already (or maybe even implemented) to gzip cached files, to avoid having to do this on the fly again and again, and if so where is it documented ?

If you are not dealing with a problem, then leave it alone.
Premature optimization will only lead to waste of time.
Also, the article you've linked is not relevant tp PHP. Which means, whatever you change will have no effect on script execution.

It's very difficult to get a straight answer out of you isn't it ? I feel like I'm wasting my time, so I shall conclude it here.

I shall interpret this as 'No there is no such solution in Smarty that I know of' and/or 'the gain in cpu/memory usage is minimal compared to the time you need to put in to get it to work that way'.

Maybe you should also try not to tell people what is important to them in terms of functionality and time allocation

If you know everything yourself, and just boast your ego by asking questions you don't need answers for, then I should assume you came here to troll people.
Othervise read my previous answer. You asking wrong questions and expect right ansers. That's just not going to happen.
You didn't even aswered my very first question. You just went on rambling about your question.

There are no wrong questions AnrDaemon.

It is a fair question to which you never replied to the point. I still don't know the answer, I just deduced, from your aggressive-style replies, that that must be the answer, or you simply don't know yourself and you're just racking up points or something because otherwise you wouldn't have replied to the question to start with ?

So I'm still unsure at this point, but with the intent to close this thread, since I wasn't going to get a straight answer anyway, not from you at least, I surmised that what I must guess. Since you are 'Smarty Elite' and you have replied, you have taken 'ownership' of this question, and I doubt very much that other people will chime in now, especially after the tone of the messages. Nobody else wants to get involved now, and i can't blame them.

What first question ? I explained that I wasn't chasing a problem, I have no measurements, I simply wanted to find out if this is something that the more Smarty-savvy people have looked into already, and if so, where it is documented, so that I can have a look and see if it's worth it to implement.

Again, don't tell me what I have time for, or what I deem wasteful, I'm quite capable of doing that myself. All I need is some straight answers and I'll derive to whatever conclusion myself.

I have allocated a time slot for myself to work on the website, after that it's product development again, and I won't have time to optimize then. So whatever I can do now, and if it makes sense, I will do, hence why I have questions, to which a simply answer suffices.

Trust me, at this point I don't feel like I'm being the troll here, just (truly) wasting my time by trying to explain once more. But that aside, I have to take in account maturity and cultural background. Those are things not easily derived on fora like this and you may very well have good intentions, I'm just not feeling it, so let's close this thread in the interest of time and sanity.

Best.

First, I wasn't the one who invented the forum "rankings".
Second, you didn't even checked, if your scripts return compressed content. You just saw a ten years (good if only ten! From the points explained, it could be twenty) old article about some stuff you don't understand and came here asking if Smarty could do it by enabling some parameters in .htaccess.
And instead of answering my first question (is that indeed the lack of compression, that affecting your site?), you went on rambling on how incompetent I am.
You even wrote a whole wall of text about it. Do you feel better by now?

I did not intend to respond anymore as I'm not going to get a good answer from you, but all your post does is tell me that you still don't understand ? So I shall try again ...

I already told you, you're asking impossible question.
But you are still pretending, that your question is right and you know better than anyone else.
You even insist that you are right, throughout the topic, even though everyone reading it laughing out loud.
Sorry, but I refuse to deal on such terms.
Go read http://www.smarty.net/about_smarty until you understand, what Smarty actually is. (Hint: it is a PHP library that is intermediate to your code and has nothing to do with output compression at any point ever.)
Your. Question. Is. Simple. Wrong.

Sigh ...
It's a good question, and the ones that aren't laughing, and actually understand the deeper mechanics, will agree. I may not work, that is something else, but it is certainly not a bad idea.

I know what Smarty is ... that's why I use it. My question was merely to find out if in this community it had been discussed already to pre-gzip cached content and serve that instead of letting Apache do it on the fly, again and again. It's something easily conceived abstractly, I just wondered if it had been explored, discussed, tested already and what the pitfalls were.

But anyway, thank you, yes, don't 'deal on such terms'. Let other more knowledgeable people chime in.

For the benefit of others that are looking into this as well, not the ones laughing (supposedly), I'll try a few things later this week. I don't know if I will bother to update this thread however, it is tainted, but at least you can Google for the following (PS. this may not work well enough to replace simply letting Apache do it (hence why the OP in the first place), but anyway)

What comes to mind is to check if the browser accepts gzipped content, via: $_SERVER['HTTP_ACCEPT_ENCODING'] and set $accept_gzipped

Save and use two cached versions, one gzipped and one not
if(!$smarty->isCached('index.tpl', $accept_gzipped))

Use an output filter to gzip if $accept_gzipped is set (and if not yet cached) (syntax not yet explored, in the filter I would let php do the gzipping).

Send a header command ( Content-Encoding: gzip ) This may actually be the tricky part as it may prevent Smarty to send further data (needs to be tested)

$smarty->display('index.tpl', $accept_gzipped);

In the .htaccess I would only set to use Apache's on the fly compression for javascript and xml then, not html, so that that is done as well, but at least Smarty-cached content is not re-gzipped all the time, possibly 1000's of times per minute (which of course is an interesting discussion topic as well because Apache may very well have this optimized as well in memory so that it would in fact be much faster than anything else ... hence why, again, the OP)

If only a knowledgeable person had responded, because I'm fairly sure I'm not the first person to come up with this.

Anyways please, 'don't deal on such terms', stop trolling this post.

You're just stupid.

I didn't expect another reply from you AnrDaemon.
Your link, as well as your input on this thread, is useless.

I see the following possibility:
Check $_SERVER['HTTP_ACCEPT_ENCODING']
If gzip can be used:
- Set up a cache_id like 'gzip' or other.
- Load the output filter. You could use isCached() check to load it only when the cache is invalid.

NOTE: If your template does contain nocache code the output filter does not run when cache file is created, but when the page is displayed.

PHP already does that.
