(Doc ID 1580685.1)
Last updated on JANUARY 20, 2017
Applies to:Oracle HTTP Server - Version 18.104.22.168.0 and later
Information in this document applies to any platform.
When displaying a page with images, often png images are not display on first access of the page, a broken image icon (eg. X) is displayed instead.
It may take a few reloads (sometimes 25+ reloads) of the page to display all the images.
mod_wl_ohs is configured to access WLS server via SSL JSSE enabled port.
Most of the time PNG images are not displayed when accessed via mod_wl_ohs.
Issue reproduces with following configuration:
-mod_wl_ohs is used
-WLS server on separate server
-WLS server is accessed via SSL with JSSE enabled
-IE and FF browsers
Issue does not reproduce with following configuration:
-mod_wl_ohs and WLS server on same server
-mod_wl_ohs access remote WLS server with non-ssl
-mod_wl_ohs access remote WLS server via ssl port but non-JSSE
-Using ProxyPass instead of mod_wl_ohs
Network trace(Wireshark) shows browser is sending reset [RST,ACK] after receiving some of the payload
-No abnormal observations seen in WLS network captures
Browser network capture
-First payload/data packet sent is 2700bytes. Received by browser as two separate packets. This is the normal behaviour, the same is observed in working baseline network captures.
-WebTier send all the data packet at once. Then it received the RST from client.
