Topic: Issue with mod_deflate on el3 server

[andrewhere]

The issue that I'm having is that when I turn on mod_deflate on an el3 server. Html/text files end up having some garbage characters at the end which messes up all the pages. It works fine, however on an el5 server.

This is what I have in my httpd.conf.

<IfModule mod_deflate.c>
SetOutputFilter DEFLATE

BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

Don't compress images
SetEnvIfNoCase Request_URI \
\.(?:gif|jpe?g|png)$ no-gzip dont-vary

DeflateFilterNote Input instream
DeflateFilterNote Output outstream
DeflateFilterNote Ratio ratio
</IfModule>

Using
Apache 2.2.3, PHP 5.2.10

The PHP zlib.output_compression setting is off so its not compressing twice.

With with browser do you get that result you posted?

Did you enable the deflate logging? If yes, what is in that log?

[andrewhere]

This is in IE8. Same results in firefox.
It looks like its not compressing properly or something.

This is what shows in the log.

"GET /test.php HTTP/1.1" 25 -/- (-%) "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; GTB6.3; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)"

This is using
LogFormat '"%r" %{outstream}n/%{instream}n (%{ratio}n%%)' deflate

I have basically only one difference in my config ... and that is insted of SetOutputFilter I have

AddOutputFilterByType DEFLATE text/html text/plain text/css

Other and unknown mime types will get ignored, which is a good thing.

However what has caught my eye is that you say Apache 2.2.3 yet I see the header telling me Apache 2.0.46. My thought is (since I got caught with this one time) is that you have somehow, probably manually, compiled and/or upgraded the el3 from 2.0.46 to 2.2.3, but quite possibly

/usr/bin/apachectl.sh (spelling may be off) is launching the old 2.0.46 still sitting in place.


Other than that ... I'm clueless

[James Blond]

maybe mod_deflate is not loaded. You can test that on the command line with

[andrewhere]

-M doesn't work with Apache 2.0, but I am loading the module in httpd.conf

LoadModule deflate_module modules/mod_deflate.so
