Apache HTTPD – AliasMatch and ProxyPass in Virtualhost

I have backend API which like this : 

http://192.168.65.203:2022/page/index.jsp

and i have Apache httpd server as a 1st layer before hit backend. I set the port as 8090.

Now i want for image file will only get from httpd server, not from backend server. So my VirtualHost look like this :

<VirtualHost *:8090>
ProxyPreserveHost On
ProxyRequests off
<Directory "/usr/share/myfile">
    Options Indexes FollowSymLinks
    AllowOverride None
    order allow,deny
    Allow from all
    Require all granted
</Directory>
AliasMatch ^/(.*.gif|.*.jpg|.*.jpeg|.*.png|.*.css|.*.swf)$ /usr/share/myfile/$1
ProxyPass / http://192.168.65.203:2022/
ProxyPassReverse / http://192.168.65.203:2022/

Problem : image still pickup from backend server. If i disable proxypass and proxypassreserve, it working fine (image can load from httpd server).

Expectation : how i can control if image is found (at alias rule) it should not go for proxypass? or is there any other method?

    Directive ! is needed. Below is the solution for my problem..

    <VirtualHost *:8090>
ProxyPreserveHost On
ProxyRequests off
<Directory "/usr/share/myfile">
    Options Indexes FollowSymLinks
    AllowOverride None
    order allow,deny
    Allow from all
    Require all granted
</Directory>
DocumentRoot "/usr/share/myfile"
ProxyPassMatch ^/(.*.gif|.*.jpg|.*.jpeg|.*.png|.*.css|.*.swf)$ !
ProxyPass / http://192.168.65.203:2022/
ProxyPassReverse / http://192.168.65.203:2022/
</VirtualHost>

    When the request is image type it will go to local file system "/usr/share/myfile" and the Directive ! is like to stop the proxy. Check here for more details for this directive.

    Replace [1] by [2] and try:

    [1] : 
AliasMatch ^/(.*.gif|.*.jpg|.*.jpeg|.*.png|.*.css|.*.swf)$ /usr/share/myfile/$1

[2] :
ProxyPassMatch ^/(*.gif)$   !
ProxyPassMatch ^/(*.jpg)$   !
ProxyPassMatch ^/(*.jpeg)$  !
ProxyPassMatch ^/(*.png)$   !
ProxyPassMatch ^/(*.css)$   !
ProxyPassMatch ^/(*.swf)$   !
