All the ESRI examples are always very straight forward, but simple and plain when it comes to headers.  In today's world we're asked to tighten down our code with the introduction of many more security headers.  This is is not my area of expertise, I'm always doing good to get my code to work!  It's my understanding some configuration can happen on the application server, as an overall configuration, while others are best managed per application. Given that I'm referencing the JavaScript API from ESRI, and not locally hosting it, coupled by the fact that we're pulling data in as services from sites outside our network, it's not as if I this can be configured based on examples provided to us from our cybersecurity 'best practice'.  There's no point in tightening it down to be non-functioning. These are the header I'm being asked about.  There may be others as time goes on: HTTP Public Key Pinning (HPKP) Header  HTTP Strict Transport Security (HSTS) Header X-XSS-Protection Header X-Frame-Options Header Header  X Permitted Cross Domain Policies Header  Content-Security-Policy (CSP) Header  X-Content-Type-Options Header  Referrer-Policy HTTP header Does anyone have any examples, words of wisdom?  I know people are likely to send me links to sites about what these are.  That's not what I want.  I have someone who can tell me generally what each is for.  What I want is syntax for settings that are likely to work.  The goal is to be more secure, but still functioning.  I've been told that implementing a CSP Header\, for example, could result in the inability to access the JavaScript API library, which is full of Function (). ...

I have used this TOC widget for several years.  This is the first time I've ever combined it with the functionality of accepting an incoming URL parameter as an argument.  The user wants to be able to zoom to a particular ID number.  The zoom works correctly.  However, somewhere along the way the changing map extent is causing a problem.  I often see errors related to the TOC.    The map extent is correct, and if you pan or zoom at all you see the map is centered correctly. Occasionally the layer DOES draw, but it's sporadic.  I have a very tight deadline (of course) and I'm up for rigging things around at this point, just to have all my layers draw every time.  I'm not even sure its the TOC that's the problem.   My test site is public facing: https://ogitest.oa.mo.gov/DNR/tmdl_imprdwater2/index.html?BUSINESSID=51215  This is how I'm checking to see if there is a URL parameter.   queryLayer.on('load', function(){ //expected input of layerid, fieldname, and layer number myURLparameter.checkURL("queryLayer", "BUSINESSID", 5); //looks for id, zooms to water body with that ID if found }); /*myURLparameter.js * Tracy Schloss, Missouri Office of Geospatial Information * Date: * Description: */ define ([ "dojo/on", "dojo/dom", "esri/urlUtils", "js/myFind" ], function ( on, dom, urlUtils,myFind ) { return { checkURL: function(layerid, field, layerNum){ var selectedVal = getIdFromUrl(document.location.href); var selectLayer = app.map.getLayer(layerid); var urlPath = selectLayer.url; var urlLen = urlPath.length; var lastPos = urlPath.lastIndexOf("/"); var findUrl = urlPath.substr(0, lastPos); if (selectedVal) { myFind.zoomSelect(findUrl,layerNum, field, selectedVal); } function getIdFromUrl(url){ //extract the county name from the url var urlObject = urlUtils.urlToObject(url); if (urlObject.query && urlObject.query.BUSINESSID) {//assumes incoming parameter of ?BUSINESSID='SOME##' return urlObject.query.BUSINESSID; //where the past element is a field name in the database } else { return null; } } } } }); ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ myFind.js /* * Tracy Schloss, Missouri Office of Geospatial Information * Date: * Description: */ define ([ "dojo/on", "dojo/dom", "dojo/_base/lang", "esri/tasks/FindParameters", "esri/tasks/FindTask", "js/myWaterData" ], function ( on, dom,lang,FindParameters,FindTask,myWaterData ) { return { zoomSelect: function(findUrl, layerNum, field, selectedVal){ var wb_type;

I have a CSV file that contains a variety of columns, including latitude and longitude.  I've not done my loading of CSV data into a featureLayer, and this is the first time I've had any troubles.  It seems to be cutting off some of my records.  I should have 211.  Looking at the data of the featureLayer, first it had just 159 records.  I've tried to upload the data multiple times, once getting just 106 records to upload, and then only 105. I feel like there is something buried in this data that I haven't spotted, but I've taken it to the plain text format, which generally strips out whatever hidden character is the problem, and back to CSV and I'm still having this problem. I tried just hosting this is a service in my local AGS environment, and I have a similar problem.  Only in that case, I see no data at all, simply an Error statement when I attempt to review the data.   I don't want to attempt to use a shape file, because the column names are all very long.  ...

I have my labelClass defined as this: HUClabelClass = new LabelClass({ labelExpressionInfo: { "value": '{HU_8_Name}', "maxScale": 250000 }, symbol: mySymbols.hucLabelSymbol() //MySymbols holds all the symbology for my project.   });        HUClayer.setLabelingInfo([ HUClabelClass ]); I'm a little lost where I should place the maxScale parameter.  It have placed it within the labelExpressionInfo and outside of it.  I've tried quoting it, and leaving it without.   No matter what combination I try, my labels draw at all scales and that's not what I want to happpen.   ...
