Re: etc_cache: cache trying hard to be smart

I’m trying

    RewriteCond %{DOCUMENT_ROOT}/textpattern/cache/$1 -f [OR]
    RewriteCond %{DOCUMENT_ROOT}/textpattern/cache/$1(\.html) -f [OR]
    RewriteCond %{DOCUMENT_ROOT}/textpattern/cache/$1(\.xml) -f [OR]
    RewriteCond %{DOCUMENT_ROOT}/textpattern/cache/$1index.html -f
    RewriteRule ^(.*) cache/$1%1 [PT,L]

but %1 capture group does not seem to work (see below). Will set an environment variable maybe…

But isn’t it reasonable to suggest that if a user wants to output an article as application/javascript, he should then url-title it name.js? This would simplify things a lot.

Just to throw extra work into the mix, I’d also need an Nginx version of the .htaccess rules – sorry!

I’ve never used %, only $. Long shot: do percent replacements need to be in curly braces? %{1}

Re: etc_cache: cache trying hard to be smart

Seemingly %n come from RewriteCond:

The problem is we need to capture them in the left hand term.

Eeek, above my pay grade! I’m only a lowly regex hacker and they normally take me aaaages in regex101 to make them do what I want reliably.

Re: etc_cache: cache trying hard to be smart

Textpattern powered websites will now serve visitors as hypertext flat-files, suspended in ‘maintenance mode’, too!

With this separation of dynamic SQL generation and static HTML delivery, in addition to the similar theming, and with the native HTML, CSS, TXP, PHP, also sections, categories, keywords, etc strict separation principle, and managed by smart and open-minded developers, Textpattern stands as exceptionally agile, neat, light, secure, and robust WWW publishing loom, unique on CMS market.

Re: etc_cache: cache trying hard to be smart

Version 0.2 of etc_static is ready. What’s new:

  • pages with no-cache, no-store, private cache-control headers or any vary header will not be cached. In particular, that’s true in dev mode.
  • pages being visited by a logged-in user will not be cached, though he can be served from public cache. It means you need to log out to populate it.
  • cache will try to append the appropriate extension, so static files should be served with the correct mediatype.

The next big step is an admin interface, so etc_static will probably merge with etc_cache.

You’ll need to update .htaccess with the following:

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

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

Repeat the last block for every mediatype you intend to use without name extension, replacing html with the latter.

Re: etc_cache: cache trying hard to be smart

If someone could translate these apache rules to Nginx, that would be ace.

Re: etc_cache: cache trying hard to be smart

Pete is the resident Nginx expert – but I’ve pestered him enough this week. Will mention it to him in due course, I’m sure there are ways to duplicate your Apache rules within it.

Re: etc_cache: cache trying hard to be smart

I guess that an URL Toolkit for the Hiawatha werbserver would much simpler, inserting two extra (bolder) lines only for the cache:

UrlToolkit {
ToolkitID = textpattern
RequestURI exists Return
Match ^/(files|images)/ Return
Match ^/(favicon.ico|robots.txt|sitemap.xml)$ Return
Match ^/themes/reguo/styles/reguo.css$ Return
Method GET Return
Match ^/(.*) Rewrite /cache/$1.html
Match [^?]*(\?.*)? Rewrite /index.php$1
}

Did I catch the right meaning of these Apache rules, Oleg?

Re: etc_cache: cache trying hard to be smart

Dunno, I’m new to rewrites. The idea is:

  • if the request type is GET
  • and if the query string (i.e. ?something) is empty
  • and cache/request_uri or cache/request_uri/index.html or cache/request_uri.html exist

redirect request_uri to cache/request_uri(.html). For example,

/section/?pg=2   ->   leave it alone
/section/        ->   /cache/section/ (will serve index.html from there)
/section/title   ->   /cache/section/title.html

but only if these .html files exist.

Am I complicating? The first version did not append .html to cached files, but they were served without content-type header, though browsers considered them as html by default.

Re: etc_cache: cache trying hard to be smart

I’m sorry Oleg, but your second plugin version do not work anymore: the cache directory isn’t created, so there is no more conversion into static files…
