[Xerte] toolkits export (solution)

[Patrick Lockley]

Thanks David,

Can  RewriteCond Request_URI export_[0-9]+$ RewriteRule ^(.*)$ $1
[QSA,E=no-gzip:1,PT,L] be put into a .htaccess?

Pat

As a belated follow up to this....

The problem we saw was that IE would pop up a warning message saying the
file was invalid. Yet, the same export url would work fine in e.g.
Firefox.

The problem was caused by the server doing deflate compression through
the following Apache config :

"
<IfModule mod_deflate.c>
        SetOutputFilter DEFLATE
        SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip
dont-vary
        SetEnvIfNoCase Request_URI \.(?:exe|t?gz|zip|bz2|sit|rar)$
no-gzip dont-vary
        SetEnvIfNoCase Request_URI \.pdf$ no-gzip dont-vary
        SetEnvIfNoCase Request_URI \.swf$ no-gzip dont-vary </IfModule>
"

One fix to this seems to be to tell the server :

<IfModule mod_rewrite.c>
    RewriteCond Request_URI export_[0-9]+$
    RewriteRule ^(.*)$ $1 [QSA,E=no-gzip:1,PT,L] </IfModule>

(i.e. for URLS like export_{NUMBER} don't do gzip compression).

An alternative solution from a PHP point of view, could be that the
mod_rewrite rule instead generates a realistic URL like e.g.
export_55.zip, rather than export_55).

thanks
David.
