ModPagespeedDisableFilters - restrict touching javascript files? it cause problems

[Jack Davis]

I found that filters rewrite_javascript and combine_javascript makes some sites buggy so I decided to disable them.

So I added this lines:

ModPagespeedForbidFilters rewrite_javascript,combine_javascript

ModPagespeedDisableFilters rewrite_javascript,combine_javascript

to file:

/etc/apache2/mods-available/pagespeed.conf

then I deleted cache (/var/cache/mod_pagespeed) and restarted apache.

But javascript files are still touched by modpagespeed (not combined or rewrited):

<script type="text/javascript" src="js/crypto/aes.js.pagespeed.ce.T_EI5FhHgN.js"></script>

<script type="text/javascript" src="js/crypto/sha512.js.pagespeed.ce.mzthzyggUD.js"></script>

<script type="text/javascript" src="js/crypto/pbkdf2.js.pagespeed.ce.pQiX_qJSuX.js"></script>

<script type="text/javascript" src="js/crypto/password.js.pagespeed.ce.qkE54i94bN.js"></script>

When I change "ModPagespeed on" to "ModPagespeed off" in config, js files are loaded directly:

<script type="text/javascript" src="js/crypto/aes.js"></script>

<script type="text/javascript" src="js/crypto/sha512.js"></script>

<script type="text/javascript" src="js/crypto/pbkdf2.js"></script>

<script type="text/javascript" src="js/crypto/password.js"></script>

...and the website works.

So I don't understand what modpagespeed do with js files if there is no enabled filter related to them.  Is possible to restrict it?

You can direct PageSpeed to leave these files alone using url control:

https://www.modpagespeed.com/doc/restricting_urls

After you disabled rewrite_javascript and combine_javascript, extend_cache was still applying to the js files.

The contents of the script files should have been unchanged, so if that broke the site then apparently something is 

depending on the original script urls to be around.

As you can see the rewritd javascript files are getting a ce like ".js.pagespeed.ce.T_EI5FhHgN.js". This say the file get "cache extended".
As far as you have disbled the rewrite javascript, I think the only "manipulation2 is extend the cache life time
