Caching http resources for increasing page speed

I found there really interesting articles about caching http resources for page speed:

XAMPP 1.8.1 Apache 2.4 AH00526: Syntax error ProxyPass worker name (...) too long. Bug

I was getting this error:

AH00526: Syntax error on line 228 of E:/Documents/Dropbox/Programs/windows7/xampp-win32-1.8.1-VC9/xampp/apache/conf/extr
a/httpd-proxy.conf:
ProxyPass worker name (http://localhost:8080/SIBismarkRestServer/webresources/com.expertix.bismark.si.entities.orderrequ
est/) too long

In this link https://issues.apache.org/bugzilla/show_bug.cgi?id=53218 Says that increasing in the mod_proxy.h file the PROXY_WORKER_MAX_NAME_SIZE value from 96 to a number that fits in your workername, ie

from
#define PROXY_WORKER_MAX_NAME_SIZE      96

to
#define PROXY_WORKER_MAX_NAME_SIZE      192

But I continue getting that error, no matter my url http://localhost:8080/SIBismarkRestServer/webresources/com.expertix.bismark.si.entities.orderrequ
est/ was 101 characters

So I had to make my url shorter

Apache: Origin is not allowed by Access-Control-Allow-Origin.

Enable in the httpd.conf file:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

In the ./extra/httpd-proxy.conf file set:

ProxyRequests Off
ProxyPreserveHost On

<Proxy *>
    Order deny,allow
    Allow from all
</Proxy>

Also add  the url you want ie, for /document:

ProxyPass /document http://192.168.2.12:8080/document
ProxyPassReverse /document http://192.168.2.12:8080/document
<Location /document>
    Order allow,deny
    Allow from all
</Location>


Finally restart apache

Apache: [warn] (OS 64)The specified network name is no longer available. : winnt_accept: Asynchronous AcceptEx failed.

If you get this error:

[warn] (OS 64)The specified network name is no longer available.  : winnt_accept: Asynchronous AcceptEx failed. 

Try adding the following line to your httpd.conf file:

Win32DisableAcceptEx

Apache: Faulting application httpd.exe, version 2.2.4, faulting module OraOCIEI11.dll, version 0.0.0.0

If your apache server suddenly restarts and your windows event viewer gets an error like this:

Faulting application httpd.exe, version 2.2.4, faulting module OraOCIEI11.dll, version 0.0.0.0


Try updating your Oracle Instant Client version.

Ie. In the server I had Version 11.1.0.6.0 and I delete that one and I installed version Version 11.2.0.2.0


That solved the problem :D
