At which point, you want the same reaction from xml2enc as from proxy_html. ! i.e. remove itself and leave your contents untouched. Not really, but that would be a viable approach in the sense of "do-the-least-unexpected". No, I would indeed like to run the xml2enc on all kinds of text (because that may ease my issue with the always-postponed character coding cleanup on my 20+ years old machines); I just want it to run where _I_ want it to run - and definitely not on compressed data. ! > [xml2enc:debug] [pid 52505] mod_xml2enc.c(250): [client 192.168.97.18:28882] AH01434: Charset ISO-8859-1 not supported by libxml2; trying apr_xlate ! !

It's proxy-html (hyphen, not underscore). Now that's a hint! Indeed, I probably missed that one - I tried with and without underscore, upper and lowercase, but likely not the hyphen... and I failed to find the place in the source where that name is declared. (Now, knowing the spelling, it is easy to find ;)) And indeed! That works like I had hoped for - with "ProxyHTMLEnable Off" and properly steered from the FilterChain, so I can suppress it on proably compressed objects. But it seems proxy-html does not even invoke xml2enc when called in the filter chain - so the whole issue vaporizes in beauty. ;) Nevertheless, the average stupid user (like me) might likely start with the most simple configuration, and might run into this, and would have a hard time figuring what is actually wrong; so we should do something about it, and spare them a night searching. ! > Finally I decided to fix the code, as good as I can.

Your fix does the job for you, but shouldn't be necessary. No, it's just that I didn't get it running discretely from the filter chain. ! I'm thinking, mod_proxy_html does the right thing removing itself. ! mod_xml2enc should do the same when inserted by mod_proxy_html. Yepp, and leave the option to insert xml2enc explicitely for other kind of files, if one wants to do that! Agreed! Whereas, in an ideal world, mod_proxy_html would not stand down, but would fixup the URLs in the stylesheet-documents as well. But then, most people are concerned about performance and use an asset-server anyway and not get such documents from the backend (while I am just using Rails as scriptable database-GUI that I can reach from anywhere in the world, disregarding performance), so public demand for this may be limited; and it can nicely be done with substitute. ! Thanks for the detailed analysis! Thanks for the (unvoluntary) invitation to look a bit deeper into the internals of that apache beast. :)) cheerio, PMc --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
