etc_cache: cache trying hard to be smart

Well, here it is. You MUST uninstall etc_static before. Then install and (re)activate etc_cache and visit Advanced prefs for basic configuration.

Even if you don’t need static cache and have etc_cache already installed, you might want to update it for improved admin tab markup.

I’m curious: I get why the txp:tag can’t be added to the filter field in the Extensions » etc_cache panel, but if it were possible to pass the filter as an attribute of the tag, like you can with reset, would the tag-in-tag variant work? My thinking was that the tag-as-attribute would be processed first and the results passed to etc_cache.

Finally, in today’s version one can set filter on the public side via id/form-less <txp:etc_cache /> blocks:

<txp:etc_cache reset="article_save">
"article_save":{"ID":<txp:article_id />}
</txp:etc_cache>

will make all subsequent cached blocks in the current article be updated only on this article’s update.

After many trial and error .htaccess cycles, I have managed to make static cache work on my plugins site. The lines to add were in my case

    RewriteCond %{REQUEST_METHOD} =GET
    RewriteCond %{QUERY_STRING} ^$
    RewriteCond /path/to/site/cache/$1 -f [OR]
    RewriteCond /path/to/site/cache/$1index.html -f
    RewriteRule ^(.*) cache/$1 [PT,L]

    RewriteCond %{REQUEST_METHOD} =GET
    RewriteCond %{QUERY_STRING} ^$
    RewriteCond /path/to/site/cache/$1.html -f
    RewriteRule ^(.*) cache/$1.html [PT,L]

where /path/to/site is the value of $path_to_site variable from Diagnostics. Now I get ~ 180ms/80ms ratio between dynamic and static pages. Not as much as Varnish could give, but better than nothing.

better than nothing.

The static pages are rather important for robustness of a website, its fault resistance, for accessibility of hypertext guides, references, books, usually published once.

My debut in regex programming :)

Let’s replace the last line of URL Toolkit ID = Textpattern for Hiawatha webserver

Match [^?]*(\?.*)? Rewrite /index.php$1

to

Match [^?]*\/(|index\.php)\?([^?]+=[^?]+) Rewrite /index.php$2

and append it by this rule-set for static delivery:

RequestURI exists Return
Match ^/$ Rewrite /cache/index.html
Match ^/([^?]+)/$ Rewrite /cache/$1/index.html
Match ^/([^?]+[^/])$ Rewrite /cache/$1.html

Still tested on Regexpal.com only, not on a live website.

If this is testing the right hand sides of each Match rule below, then Hiawatha is much easier to configure than Apache.
