Content encoding error when requesting the unified CSS file

[mick...@kikuta2008.com]

Hi,

Once in a while a request to the unified CSS file returns with a content encoding error. We only started seeing this recently on mps 1.11.33.2-0, and never saw or see it on 1.9.32.14-0.

I'd appreciate any advise you might have on this matter :-)

Thanks,

Mickey.

This looks like an answer by jmarantz related to a similar report:

https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/mod-pagespeed-discuss/Mgm6ZbAeJms/C5EpA5mVBwAJ

If configuring the following resolves the problem, could you let us know?:

 ModPagespeedHttpCacheCompressionLevel 0

We'll give it a try and let you know.

Thanks for the quick reply :-)

We would very much like to get to the bottom of this, but could use some help with more detailed description of when & how often the problem happens, conf files, server configuration, etc.

Thanks!

Per Otto's question, please do post if this seems to fix it!

Setting ModPagespeedHttpCacheCompressionLevel  to 0 closed this issue.

It's hard to say how often as it behaved randomly. I'd say 1:20 requests but it's a guess. Might be also related to first time seeing the page. As for the conf -- see the diff I posted on the other question. If you need details from httpd conf, please let me know and I'll be able to send it to you personally. I can't post it in public.

Idea: can it be related to the CSS file itself? If you need it (either processed or not) please let me know and I'll see you have it.

Anyway, thanks for helping with this :-)

Mickey.

This is a combined/minified file, right?  That is, it has a URL leaf that looks something like   A.file1.css+file2.css.pagespeed.cf. ...

The "A." and ".cf" mean that it was minified.  The "+" means that it was combined.

I doubt it is related to the CSS itself, though it might be related to the way the origin CSS was generated.  For example, if the origin CSS was saved on the disk as a gzipped file by (say) a WordPress extension, and then accessed by mod_pagespeed directly from the disk via LoadFromFile -- that might be relevant.

Still, seeing the actual CSS content can't hurt.  But what's really important is the server configuration, which we can get by private-message.

Yes.

This is not the case. The CSS is a part of our version and is static.
