The code also sniffs the user agent string for 'Safari' and sets a mysterious 'uplevel' ClientTarget value, a pattern repeated across multiple pages in the codebase. The piece pokes fun at unclear naming, string-based flags, and browser sniffing as bad coding practices. ## Full article daily.dev links to this article rather than hosting it.

This is just an old application doing old application things. The single line is a symptom rather than the crime. I have never once seen a ClientTarget set on the basis of a user agent turn out to be a good idea in the long run. Naming the flag uplevel would have helped whoever read it next, but only a little. ## Similar posts on daily.dev - [Classic WTF: One-and-a-Half-Tiered Application Design](https://daily.dev/posts/classic-wtf-one-and-a-half-tiered-application-design-u5pu5ycfn) · The Daily WTF · 1 upvotes · 0 comments - [Antiquated HTML Snippets and Artefacts](https://daily.dev/posts/antiquated-html-snippets-and-artefacts-oaojgodsy) · Lobsters · 2 upvotes · 0 comments --- Tags: [#aspnet](https://daily.dev/tags/aspnet), [#c#](https://daily.dev/tags/c#) [View this post on daily.dev](https://daily.dev/posts/extremely-one-line-oirzjyhit) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Extremely One Line","url":"https://daily.dev/posts/extremely-one-line-oirzjyhit","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/extremely-one-line-oirzjyhit"},"datePublished":"2026-09-16T11:27:57.688Z","dateModified":"2026-10-14T02:24:04.882Z","description":"A humorous look at a code snippet from an old ASP.NET application where the entire Page_PreInit function is crammed onto a single line despite Visual Studio's...","image":"https://media.daily.dev/image/upload/s--OHB84bZF--/f_auto/v1722860399/public/Placeholder%2010","thumbnailUrl":"https://media.daily.dev/image/upload/s--OHB84bZF--/f_auto/v1722860399/public/Placeholder%2010","isAccessibleForFree":true,"articleSection":"The Daily WTF","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"The Daily WTF","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/d21a6aa61a7244d893a3b3284df8e2ef","url":"https://daily.dev/sources/thedailywtf"},"commentCount":2,"discussionUrl":"https://daily.dev/posts/extremely-one-line-oirzjyhit","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":9},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":2}],"keywords":"aspnet,c#","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"The Daily WTF","item":"https://daily.dev/sources/thedailywtf"},{"@type":"ListItem","position":3,"name":"Extremely One Line"}]} {"@context":"https://schema.org","@type":"WebPage","@id":"https://daily.dev/posts/extremely-one-line-oirzjyhit","comment":[{"@type":"Comment","text":"I have seen this exact pattern before: the whole PreInit crammed onto one line because the autoformatter kept undoing the formatting, and someone gave up fighting it.
