Chrome-only Issue: Serving images using a servlet. One image loads, one image doesn't -

edit:

i have page contains following html code:

<img src="/static/ads/1111.png"> <!-- 1 --> <img src="/static/2222.png"> <!-- 2 --> 

when load page, image no. 1 cannot displayed. image no. 2 displayed.

checking image request in chrome devtools's network tab, request "pending".

what's weirder, when directly access image no. 1 in http://localhost:8080/static/ads/1111.png, image loads.

this issue seems affect google chrome. tested in firefox , works there.

for chrome console error:

port error: not establish connection. receiving end not exist.

when compare request headers of image no. 1

cache-control:no-cache pragma:no-cache referer:http://localhost:8181/index.html user-agent:mozilla/5.0 (macintosh; intel mac os x 10_8_3) applewebkit/537.31 (khtml, gecko) chrome/26.0.1410.43 safari/537.31 

vs image no. 2

accept:*/* accept-charset:iso-8859-1,utf-8;q=0.7,*;q=0.3 accept-encoding:gzip,deflate,sdch accept-language:en-us,en;q=0.8 cache-control:no-cache connection:keep-alive host:localhost:8181 pragma:no-cache referer:http://localhost:8181/index.html user-agent:mozilla/5.0 (macintosh; intel mac os x 10_8_3) applewebkit/537.31 (khtml, gecko) chrome/26.0.1410.43 safari/537.31 

there big difference. know what's going on?

more information

i'm using balusc's fileservlet serve files found outside web-app directory.

my web app uses struts2 framework.

my web.xml:

<filter>     <filter-name>struts2</filter-name>     <filter-class>org.apache.struts2.dispatcher.ng.filter.strutsprepareandexecutefilter</filter-class> </filter> <filter-mapping>     <filter-name>struts2</filter-name>     <url-pattern>/*</url-pattern> </filter-mapping>   <servlet>     <servlet-name>fileservlet</servlet-name>     <servlet-class>com.fileservlet</servlet-class> </servlet> <servlet-mapping>     <servlet-name>fileservlet</servlet-name>     <url-pattern>/static/*</url-pattern> </servlet-mapping> 

i have excluded path in struts.xml so:

<constant name="struts.action.excludepattern" value="/static/.*"/> 

from jb nizet:

are sure you're not using ad-blocking plugin filter out images fom ** /ads/ **?
