Hi, I wrote an httpprovider to generate media playlist. However Wowza server doesn’t invoke my http provider according to the request filter in VHost.Xml; Below is part of my Vhost.xml file. If a client sends a request like "[http://xxx/myStream/yshenmediaplaylist\_bandwidth\_64000bit?serverid=xxx&username=xxx;](http://xxx/myStream/yshenmediaplaylist_bandwidth_64000bit?serverid=xxx&username=xxx;) This request should be handled by my own httpprovider. com.yshenWowza3.HttpProviders.CupertinoServer3 _yshenmediaplaylist_ none However, in the debug mode, no break points is triggered. Instead, the wowza server returns the version info…☹ In addition, if the client request is like “[http://xxx/myStream/yshenmediaplaylist\*](http://xxx/myStream/yshenmediaplaylist*) (ends with '_’); The request will go to my http provider. So weird… can I put only one "_” in the filter? Thank you in advance! 🙂 ---

Hi, Where did you place the custom HTTP listener? Is it above or below the Server Version HTTP listener? Zoran ---

Hi Support for displaying WebVTT thumbnials is buit into some players. One such player is JW Player. They have their own support article on how to do this [here.](http://support.jwplayer.com/customer/portal/articles/1407439-adding-preview-thumbnails) The thumbnails must be stored and referenced on a Webserver, such as the webserver you are hosting the player from.

Sure. I put it above the provider with request filters “\*”. com.yshenWowza3.HttpProviders.CupertinoServer3 \*initsystem|\*masterplaylist|_yshenmediaplaylist_ none Server\_ID 127001 String com.wowza.wms.http.HTTPCrossdomain \*crossdomain.xml none com.wowza.wms.http.HTTPClientAccessPolicy \*clientaccesspolicy.xml none com.wowza.wms.http.HTTPProviderMediaList \*jwplayer.rss|\*jwplayer.smil|\*medialist.smil|\*manifest-rtmp.f4m none com.wowza.wms.timedtext.http.HTTPProviderCaptionFile _.ttml|_.srt|_.scc|_.vtt none com.wowza.wms.http.HTTPServerVersion \* none ---

By the way, I found that if the request URL ends with “.m3u8” Wowza will just return the master playlist without invoking my HTTP Providers at all, even if I set request filters in VHost.Xml. I want the request to be processed by my own functions so that I can return customized playlists to the clients. ---

I found the answer myself. By default, all the incoming requests ending with “.m3u8, m3u, aac, mp3,ts” will be directly processed by Wowza built-in class, without going to custom http providers or modules. To change this default behavior, we have to modify the file Wowza\_dir/conf/HTTPStreamers.xml. The file is quite self-explanatory. If you couldn’t find this file. Just download one from Internet and copy it to conf/ folder.
