Hello list,

```
I hava a nginx config problem , Please help look !
I use proxy_cache and ssi.

```

_nginx config :_  
ssi on;  
ssi\_silent\_errors on;  
ssi\_types text/shtml;

proxy\_temp\_path /cache/proxy\_temp;  
proxy\_cache\_path /cache/proxy\_cache levels=1:2 keys\_zone=tmp\_cache:2000m  
inactive=10000d max\_size=200G;  
proxy\_next\_upstream error timeout invalid\_header http\_504 http\_500  
http\_502 http\_503;

_example:_  
\*  
\*  
[http://x.com/1.shtml:](http://x.com/1.shtml:)  
  
hello world1 !  
  
\<\html\>

```
    http://x.com/2.shtml:
    <html>
     hello world2 !
     <!--#include virtual="/include/foot.html"-->
    <\html>
     .......

     http://x.com/include/foot.html:
    <html>
     old, i am include info !
    <\html>

```

_problem:_  
\*  
\*  
Edit this file: [http://x.com/include/include/foot.html](http://x.com/include/include/foot.html)  
  
new, i am include info !  
\<\html\>

```
  I use ngx_cache_purge to clear the cache :

```

[http://x.com/include/include/foot.html](http://x.com/include/include/foot.html)

```
  But do not take effect cache these pages :

  open http://x.com/1.shtml
  the content is :
    <html>
     hello world1 !
     old, i am include info !
    <\html>

  open http://x.com/2.shtml
  the content is :
    <html>
     hello world2 !
     old, i am include info !
    <\html>

  I have to clear the cache in order to take effect :
  http://x.com/purge/1.shtml
  http://x.com/purge/2.shtml

  open http://x.com/1.shtml
  the content is :
    <html>
     hello world1 !
     new, i am include info !
    <\html>

  open http://x.com/2.shtml
  the content is :
    <html>
     hello world2 !
     new, i am include info !
    <\html>

```

If I have a lot shtml files ,Must be more clear the cache.  
[http://x.com/purge/1.shtml](http://x.com/purge/1.shtml)  
[http://x.com/purge/2.shtml](http://x.com/purge/2.shtml)  
[http://x.com/purge/3.shtml](http://x.com/purge/3.shtml)  
[http://x.com/purge/4.shtml](http://x.com/purge/4.shtml)  
[http://x.com/purge/5.shtml](http://x.com/purge/5.shtml)  
[http://x.com/purge/6.shtml](http://x.com/purge/6.shtml)  
…

I just need to clear a cache: [http://x.com/purge/include/foot.html](http://x.com/purge/include/foot.html) ,  
all  
SHTML pages to take effect.  
Is there a way to solve?

Thanks in advance 🙂

Hell FoxBin,

can you please post your whole proxy\_\* - config?

since your footer.html gets included and displayed via 1/2/3.html, this  
file  
itself will  
never get cached, thus never can be purged, because it becomes part of  
the  
output of 1/2/3.html.

“simple” caching is done based on URLs

regards,

mex
