Proxy Server issue


User (Legacy)

Hi

Currently we are deploying access to a our web site which uses chartfx 6.2

to display graphs of energy usage. We have hit a snag when clients reside

behind a proxy server. We were using SSL and users could log into our web

site however when they tried to generate a chart it would result in a

connectfailure.

I've gotten one of the clients to connect without SSL and he received the

following error "Failed to download chart ProtocolError

ProxyAuthenticationRequired (407)" when trying to download the chart. The

users can surf our website and it is only the chart generation that results

in an error.

The client has all their .NET trust levels set to Full Trust and they can

download the .NET assemblies. I checked using the gacutil and all the

correct .NET assemblies were being downloaded. When the client doesn't go

through the proxy serve he is able to download the chart.

I have also set the chart.ProxyUri = "" since this should automatically

detect the default proxy server in IE. I do not have access to our clients

proxy and he has indicated they will not change the settings.

Is there anyway to make this work?

thanks

Are you positive on this ? Note that with Medium or Low Trust, the client

will be able to download the assemblies and ChartFX will be able to download

the chart files BUT in order to work through the proxy we need to use .NET

methods that do require full trust.

Do you know if these users are using "dynamic proxy" settings ? The

documentation for GetDefaultProxy states that

"The GetDefaultProxy does not pick up any dynamic settings that are

generated from script run by Internet Explorer, from automatic configuration

entries, or from DHCP or DNS lookups."

Our current build already defaults the ProxyUri to ""

We implemented a feature called EmbeddedData where the data for the chart is

saved inside the HTML page (more specifically as a PARAM tag) instead of

being a separate URL. This helps with proxy issues as well as webfarms. You

can use turn on this feature by editing the ChartFX.Internet.Config in the

bin folder of your web application. e.g.

<CfxIESettings>

<EmbeddedData>true</EmbeddedData>

</CfxIESetting

Note that this feature will increase the size of the HTML page but the chart

client will not have to issue a separate URL request to download the chart

data and settings. You may want to play with this and check how it works in

your particular scenario.

Thanks for the good info.

1. Currently I don't have a ChartFX.Internet.Config file in my bin

directory. Should I just create one with a text editor?

2. I edited my html and added EmbeddedData="True" which resulted in me

getting a "Missing License Tag" error. I then set MainClient="False" and the

situation resolved itself. When using EmbeddedData="True" does chartfx

require MainClient="False"?

I am using chartfx.internet.client 6.2.1728. I have several outside

javascript commands that change chart properties. If I can't use MainClient

the I need to modify them all as follows.

profile.chart.chart.AxisX.LabelAngle == 45

to

profile.chart.AxisX.LabelAngle == 45

Thanks

MainClient is compatible with EmbeddedData provided you have a recent 

version of ChartFX.MainClient.Dll,

Can you post the file version you are using ?

Can you check if you have a more recent version of this file in your machine

?

We released a hotfix recently (that required some changes to MainClient) so

I am posting the newer version of this DLL, make a backup copy of the one

your are using now and check if this fixes your issue.

I updated the ChartFX.MainClient.dll and it all works.

Thank you very much. It's going through the proxy server without problem.
