Proxy Cache?

omarchicas
I'd like to have cache for performance on the server proxy. Would adding the modifications manually be overwritten when making a change?

Add this to /var/chroot-reverseproxy/conf/httpd.conf: 

    CacheEnable disk /

    CacheRoot "/var/cache/mod_proxy"

    CacheDirLevels 3

    CacheDirLength 5

    CacheIgnoreCacheControl On

    CacheMaxFileSize 100000000

    CacheIgnoreNoLastMod On

    CacheMaxExpire 1209600

    CacheIgnoreQueryString On

    it wouldn't work at all as the proxy isn't based on squid anymore.  You might actually crash the proxy or do even more damage.  Leave it be.

    That is not a squid config, that is apache disk cache feature, which you can enable to allow caching while reverse proxy on apache.

    The statement will work if the module is loaded and ignored if the module is not loaded, so it won't crash the apache server, however i'm wondering that if I place this would apache be overwritten when you make a change on webadmin, for example if webadmin uses apache conf templates.

    It would probably be a good idea to enable this for WAF on UTM to allow caching on the reverse proxy services.

    @omarchicas:  The problem that you'll get into here is that manual configuration from the backend is not only unsupported, support won't assist with systems where this has been done until the customization has been removed.  So, the vast majority of business users won't do this.

    That being said, it's very likely that anything which triggers a restart of the service will overwrite the changes.  Even if they survive a service restart, installation of any up2date package will definitely overwrite the changes.

    Hi, Omar, and welcome to the User BB!

    I would think, given the relative throughput of LANs and WANs, it would be better to put the cache on the webserver than in the security gateway.  Having said that, I should also say that I don't activate caching for the Web Proxy in any of my clients' Web Filtering configurations.

    Cheers - Bob
