Dotaz: Apache2 a SSI

[jan.rok]

Dobrý den, nedaří se mi rozchodit podporu SSI na Apache2. Udělal jsem si čistou instalaci Apache2 a podle návodu doplnil do konfiguračního souboru:

LoadModule include_module modules/mod_include.so

Directory />

Options FollowSymLinks +Includes

AllowOverride None

/Directory>

dále

Options Indexes FollowSymLinks +Includes

Přesto se mi SSI nezobrazí. Kde dělám chybu? Přiznávám, že Apache jsem rozchodil bez hlubší znalosti, pro mé účely zatím stačí. Ale u SSI jsem narazil.

Děkuji za postrčení. JR.

SSI neni SSL

Kazdopadne bych se kouknul do logu (po nejake chybe treba), a taky nevime, jak to vlastne testujete (ze to nefunguje).

[Hodza]

Je sorry, neumim cist...

[jan.rok]

V logu není nic.

Testuju tak, že mám soubor test.htm, v něm

<!-- #include virtual="a.shtml" -->

Soubor a.shtml obsahuje jen text

Vše běží na windows. Že to nefunguje usuzuju z toho, že se mi text z a.shtml nezobrazí při načtení stránky test.htm.

Apache je na win nejakej rozbitej - ale nejspis je to tim, ze jsou rozbity Win Nicmene...

<!--#include virtual="a.shtml" -->

...bez mezery mezi -- a # taky nejede?

[outsider]

Jo a samozrejme je to potreba testovat na souboru s koncovkou .shtml

[jan.rok]

Ani bez té mezery... Koncovku shtml mají teď oba soubory.

[melkors]

Neni, cirou nahodou, zapnuty SELinux nebo neco podobneho?

[jan.rok]

Není, mám to pod Win.

Jak tak koukam do manualu, tak vam v te konfiguraci chybi SetOutputFilter INCLUDES ... (pripadne XBitHack on)

Configuring your server to permit SSI

To permit SSI on your server, you must have the following directive either in your httpd.conf file, or in a .htaccess file:

Options +Includes

This tells Apache that you want to permit files to be parsed for SSI directives. Note that most configurations contain multiple Options directives that can override each other. You will probably need to apply the Options to the specific directory where you want SSI enabled in order to assure that it gets evaluated last.

Not just any file is parsed for SSI directives. You have to tell Apache which files should be parsed. There are two ways to do this. You can tell Apache to parse any file with a particular file extension, such as .shtml, with the following directives:

AddType text/html .shtml
AddOutputFilter INCLUDES .shtml

One disadvantage to this approach is that if you wanted to add SSI directives to an existing page, you would have to change the name of that page, and all links to that page, in order to give it a .shtml extension, so that those directives would be executed.

The other method is to use the XBitHack directive:

XBitHack on

XBitHack tells Apache to parse files for SSI directives if they have the execute bit set. So, to add SSI directives to an existing page, rather than having to change the file name, you would just need to make the file executable using chmod.

chmod +x pagename.html

A brief comment about what not to do. You'll occasionally see people recommending that you just tell Apache to parse all .html files for SSI, so that you don't have to mess with .shtml file names. These folks have perhaps not heard about XBitHack. The thing to keep in mind is that, by doing this, you're requiring that Apache read through every single file that it sends out to clients, even if they don't contain any SSI directives. This can slow things down quite a bit, and is not a good idea.

Of course, on Windows, there is no such thing as an execute bit to set, so that limits your options a little.

In its default configuration, Apache does not send the last modified date or content length HTTP headers on SSI pages, because these values are difficult to calculate for dynamic content. This can prevent your document from being cached, and result in slower perceived client performance. There are two ways to solve this:

   1. Use the XBitHack Full configuration. This tells Apache to determine the last modified date by looking only at the date of the originally requested file, ignoring the modification date of any included files.
   2. Use the directives provided by mod_expires to set an explicit expiration time on your files, thereby letting browsers and proxies know that it is acceptable to cache them.

V konfig. souboru mám mj.:
LoadModule include_module modules/mod_include.so
# First, we configure the "default" to be a very restrictive set of
# features.
#
<Directory />
Options FollowSymLinks Includes
AllowOverride None
</Directory>
XBitHack on

A pak níže ještě:
AddType text/html .shtml
AddOutputFilter INCLUDES .shtml
AddHandler server-parsed .shtml

Již vše funguje. Chyba byla v tom, že jsem konfigurační příkazy týkající se SSI umístil na špatné místo v souboru.
Díky všem za rady. JR
